Lightroom Develop and library mode picture differences on macOS

[defaultf7zspzlbt06q]

I have a problem in Lightroom with the display shown to me.
After my editing in the development area it is in the library area much darker and looks like a bit unedited. (see the pictures below)

Also if I´m in the develop area and I zoom inside to 100% it also looked unedit/darker. (Video - the green of the grass changed after zooming in)
The strange thing is that it only affects some pictures in my folder but not all.
And It appaered from one day to another. No LrC or MacOS update.

Things I have tested:
I changed to many different color profiles from my MacBook Pro M1 but everywhere it is the same. I also tested it with an external Display it is also the same.
I cleared all my 1:1 Previews and Standard Previews. I also generated them newly. I cleared my Cache Folder. I optimized my LR catalog. I reboot my MacOS machine. I deactivated the GPU acceleration and activated it back again.

I use MacOS 14.5 with LrC 13.2

I hope someone can help me.

Hey, @defaultf7zspzlbt06q. Welcome to the Lightroom Community. I'll need more info to help you figure this out.

Does this happen after a specific series of steps? Please share the system info from Lightroom Help > System info > Copy & paste into a text document > upload & attach here.

Where is the catalog stored? On the internal, or external drive? 

Start by resetting Lightroom Classic following the second (manual) method from this article: https://adobe.ly/3OsrHkc

Once this is done, try these suggestions:

Launch Lightroom Classic with a new catalog by pressing the OPT key at launch & create a new catalog.

Test with a few images and create 1:1 previews from the import menu & check if that helps.

Let me know how it goes. Thanks!

Hello Sameer,

the problem is solved. I tried a few different things and then it worked. It was a bit confusing because I don't really have a clue what solved my problem.

Sorry that I don´t closed the Thread here.
