2020 MacBook Pro 16 inch no longer recognizes installed GPUs.

I was having no problem with Painter (although I admit that I am a raw beginner) until today.  Was getting good performance scores despite only have 4gb GPUs installed.  However, this morning I imported somebody else's workspace and now Painter won't recognize my GPU.  Also I have something like 4 or 5 color wheels that I can't get rid off.  I include screenshots and if anybody can help me or tell me where and how to rectify the problem I would certainly be very appreciative.
