Lightroom Classic Keyword Typing Turns White

This is such an unusual issue, no one at Adobe has ever heard of it and cannot fix it. I have spoken to Adobe  Support reps at least 10 times and they have tried various things to attempt to fix it. It is happening on both my Mac Desktop and Mac Laptop

After selecting a group of photos to insert the keyword, the type in keyword box  turns white and I cannot see what is being typed in the box although it is still typing the word I tried to type. If I close LR and reopen the box is back to normal for a short time. It will happen immediately if I select a group of photos to add/delete a keyword. Needless to say, it is frustrating to not be able to see what I am typing in the keyword box. This has been happening for over 2 years so it has been occurring through Lightroom and Apple operating system updates
Adobe has deleted LR and re-installed it several times, has changed the graphics processor in Preferences/Performance from Auto to Custom, increased the Camera Raw Cache Settings to a maximum size of 100 GB, deleted/reinstalled preferences and fiddled around with various other things. I have also changed the Mac settings Appearance from dark to white. Nothing has worked. Most recently, Adobe said to ask Apple, who wants no part of this.

This is frustrating
