Photos switching to black and white in develop mode

[Everyday Life Photography]

My photos are turning to black and white when I look at them in develop mode. Even if I change them to color when I go back to them again they are in black and white. Can someone pleaase help me figure out why this is happening? I have been using lightroom for years and years and have never had this happen. 

Thanks!

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

"been using lightroom for years and years"- So which Version NUMBER of Lightroom are you using?

This is the 'Cloud based' forum, yet I suspect you have the 'very old' perpetual version or Lightroom-Classic.

Copy and post the report you get from the MENU > Help > System Info...

Are the thumbnails in Grid view in color?

Only in Develop module they automatically turn B&W (or grey)?

What do you mean by- "go back to them again"?

Color problems when changing modules is often caused by an incompatible, faulty, or corrupt Monitor profile.

Try a test using the sRGB profile for your monitor to see if that is the problem.
