Contact Adobe. This via a Chat. Before doing so, prepare your notes and information ahead of time as to be more efficient in communicating. Your info that you have posted in your Discussion is a start for the description, and probably have a copy of your LrC /Help/System Info/ as a text document on hand, so that you can paste or attach that into the chat.   To accomplish the Chat, bring up an Adobe webpage, and click on the Chat button. (see image below) This will start a Chat. At first the Chat will be with a chatbot, Typing “Agent” into the chat text field will bypass the initial chatbot. If an agent does not enter the chat then be assertive in requesting an actual Adobe Tech join in the chat.   In the Chat include (as mentioned above) a description of the issue, and probably your System Info.

"but I have no date info as I auto update." "windows updates are set to auto."   Many of us under no circumstance allow the OS or the various Apps to just willy-nilly auto update. We do not trust the software developers to not foul up. Not for OS, not for Programs, and not for firmware   Many of us wait several days if not a couple of weeks, for any issues to appear for other users, and/or in discussions on blog and info sites.  This very Adobe Lightroom Classic community for example, where you can see that around LrC v13 the Sync to Cloud got very fouled up.   That Windows upgrade to 24H2, some very specific computers have had issues, so bad that Windows pulled the upgrade back for computers with specific hardware attached.   some examples:   https://www.bleepingcomputer.com/news/microsoft/windows-11-24h2-upgrades-blocked-on-some-pcs-due-to-audio-issues/ https://www.bleepingcomputer.com/news/software/nvidia-shares-fix-for-game-performance-issues-with-new-nvidia-app/   Not that the Windows update is your issue.

What lock file, I do not see it in that screenshot. Is it lower down? But what is with that first file? PS icon, but LrC file, and a description of lock file but no file extension indicating such??   Ahhh, you did a search, that just confuses the issue. Actually select the folder your actual current working catalog is in, and show that folder.   Also, you clearly have MS account in use to log on to your Windows computer, fine, but that forced the use of OneDrive upon you, specifically auto sync of various user system library's with OneDrive. (User, Documents, Downloads, Pictures, Videos, Music, others?)  As a result your LrC catalog is syncing to OneDrive. Some say that is a solution made in heaven, others say hell. That situation can slow LrC performance down. Each and every edit in the catalog and it syncs to OneDrive. And if you are having a bad Internet access day, even worse. And in rare situations, the catalog can get corrupted. Consider either disassociating the folder the catalog is in with OneDrive, or create a root level folder, that Is not syncing to OneDrive, and move the catalog (make sure you have good backups) name the folder as you see fit, but not pictures, etc, perhaps something like MyPhotography, MyLightroom,Rumpelstiltskin, GrumpOldBugger, anything other than the existing user system folders.     ...

I think I am missing something in this discussion, at least at this point.   First up, let my state the following (in case I am full of it)   Lightroom Classic library previews are used in the Library, Book, Print, and Web modules, and these include any Loupe Views, Grid Views, Navigation Panel Views, and the Filmstrip In the Develop Module, the Navigation Panel, and the Filmstrip, are those very same Library Previews. In the Develop Module, in the Loupe View, you see a preview contained in the Camera RAW CACHE. Smart Previews can be useful if you like to disconnect from wherever you keep your original photos. (Like external  media, think Ext hard drives). Some find that to a  be speeder as well (Smart Previews being so small, but that is a false hope) . But frankly, it is a pain in the workflow. Embedded Previews can speed up Importing. But frankly are a pain after that. I would avoid.   (REF) : https://mastering-lightroom.com/complete-guide-lightroom-previews/ https://digital-photography-school.com/6-types-lightroom-previews/       And as for what occurs during editing:   If you are in the Develop Module, and you are altering one or more photos. Then as you make those Develop edits, the Library previews should be getting updated. Including those you actually see while in the Develop Module (The Navigation Panel, and the Filmstrip). You should not need to first make some Develop Edits, then go and tell LrC to update the Library previews. If you are applying Develop mods in batch, that should not change (although a bit more time may occur). If you accomplish any Develop Module change, and then go into the Library Module and you see no change in that preview, then something is wrong. This goes for the Grid view, the Loupe View, the Filmstrip (in any module, they are library previews by the way) ... View more

Not an embedded preview user, so my lessons leanrend is zero. But, (and you may have already done this) at Google (using the bloody nee AI) If I search on "Lightroom Classic Embedded Preview Problem" I see this: ____________________________________________________________________________________________ A "Lightroom Classic embedded preview problem" usually refers to a situation where the preview image displayed in Lightroom doesn't accurately reflect the actual image due to the camera's embedded preview being used, which can sometimes be lower quality or not color-managed correctly, leading to discrepancies when applying edits in Lightroom; this can be resolved by forcing Lightroom to generate its own "standard preview" instead of relying on the embedded preview. Key points about embedded previews in Lightroom:   What they are: Embedded previews are small, low-resolution images generated by the camera and stored within the RAW file, allowing for faster initial display when importing photos into Lightroom.   Why they might be problematic:   Color accuracy: Since they aren't color-managed by Lightroom, the embedded preview might not accurately represent the actual colors in the RAW file, especially if camera profiles are applied. Quality issues: Depending on the camera, the embedded preview might be too small or have low detail, leading to a poor visual representation in Lightroom.   How to address embedded preview issues in Lightroom: Import settings:   Choose "Standard Previews" when importing: Select the option to build standard previews during import instead of relying on embedded previews. "Replace Embedded Previews with Standard Previews during Idle Time": In Lightroom preferences, enable this setting to automatically replace embedded previews with standard ones when your computer is idle. Manually generate standard previews:   Select the image: Choose the image where you want to see a more accurate preview. Go to "Library > Previews > Build Standard-Sized Previews": This will force Lightroom to generate a higher quality preview based on the RAW data.   ... View more
