Weird colors on Lightroom Classic thumbnail photos

[Rhonda1223]

Help! I just opened Lightroom Classic and all of the thumbnails have wonky colors, mostly reds and blues. The main photo on the develop part of the screen is totally fine, but all of the thumbnails have this weird coloring.  Not sure what happened. but I appreciate any suggestions to rectify it!

Please post a screenshot that illustrates the issue.

Do not attach the screenshot, use the Insert Photos button in the toolbar.

I was able to resolve the problem by changing the sRGB profile set to correct a corrupt profile. But thank you for your response!

Attaching a screenshot is fine.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post.

I was able to solve the problem by correcting the defective color monitor profile. But thank you for your willingness to assist!

Possibly a defective or corrupt monitor profile. Test this- sRGB PROFILE SET 

Also try turning off the [Use Graphics processor] option in {Preferences > Performance > camera raw}

Thank you for these suggestions! I tried the sRGB test, and it worked to restore the correct colors! With regard to turning off the Graphic Processor option in Preferences>Performance, I did that, but then got a message that enabling it would improve performance, so I turned it back on. It did not seem to make a difference with the problem I had been having. Thanks again!
