P: v14.5 Lightroom has encountered problems reading this photo | Round circle ‘!’ warning on Images

Any news?

Any feedback here from Adobe?

Still waiting for a feedback from someone at Adobe 🤷🏻‍♂

Anyone here from Adobe?

Any expert human here who can take care of this annoying bug?

Can you please move this back to BUGS?
I am an IT MANAGER with 28 years experience and I have spent the whole mrning running tests, case by case, step by step, and I believe what I have found is indeed a bug of v14.5, considering that this was not a problem on previous version.
Thanks

Well... I found where the problem is, and still believe it's a LrC v14.5 bug.

Below the two problematic test images: by removing the brushes in the masks (one on top image, two on below image) the exclamation mark disappears.
Re-adding manually a similar brush in the same mask, the exclamation mark reappears.
If I completeky remove the whole mask and recreate it manually in the same way, the exclamation mark does not reappear.

OS: Windows 11
LrC VERSION: 14.5
NOTE: the problem below appeared only after upgrading to v14.5

21 RAWs (out of almost 30.000) have a round black exclamation mark: this is not the missing photo mark, which is square light.
If I click on the exclamation mark, I see error "Lightroom has encountered problems reading this photo, you are not allowed to edit this image".

Yet, I can still enter develop module and edit the photos without any problem: the editing history is there, I can zoom in at 100% (generating the 1:1 preview), I can change sliders, export... Everything...
PS: I do not use smart previews.

The 21 problematic photos are in different folders and have different dates.
The files can be opened by any other program, including Fast raw Viewer.

The files are not locked or protected.

The files are not in any synced folder: they are on a reliable professional and fast 4TB SSD that has been carefully re-tested without any issue.

For a couple of problematic photos, I tried the following:
- deleted the photos from file explorer

- the square light exclamation mark replaced the round dark exclamation mark
- restored the files from three differente sources:
 1- the original file
 2- a backup from a second HD
 3- a backup from Amazon Photos

- in all three cases above the black round exclamation mark came back

For both of the above photos I then run the following test:

- created a new folder
- copied there the two problematic pictures
- renamed them (just not to mess with file names)
- imported into catalog
- edited pictures
- no problem
- copied edits from original pictures

- pasted edits on newly imported pictures >>>> boooom! Exclamation mark appeared on newly imported pictures

- clicking on RESET for newly imported pictures did not immediately remove the exclamation mark

- played a bit with other pictures

- came back to newly imported pictures and exclamation mark was not there anylonger

The on one of the newly imported photo I run the following test:
- copied  and pasted edits one by one per group: the exclamation mark appeared only when I pasted masks

I run this test:
- created a new folder
- copied there two of the problematic pictures
- renamed them (just not to mess with file names)
- imported into catalog
- edited pictures
- no problem
- copied edits from original pictures

- pasted edits on newly imported pictures >>>> boooom! Eclamation mark appeared on newly imported pictures

- clicking on RESET for newly imported pictures does not remove the exclamation mark

THERE IS OBVIOUSLY A BUG in new version of LrC

Hey @Giovanni Stoto, 

It looks like the file is missing, and you're editing the smart preview. If you move the photo outside of Lightroom Classic, it won't know where it is until you relink it. Try following the steps in this article:  https://adobe.ly/4mYtCfg

Let me know if that doesn't work.
