Loss of colors and texute

Hi, I noticed that I'm not the only one having problems with losing colors and textures on some imported objects.

But this started when I changed the video card from Nvidia GTX750§Ti to Radeon RX570 8GB
.
I have already tried more than one driver and I have also formatted the pc, but the problem persists.

I also tried to reopen an old project and it looks good. But when I insert a "corrupted" object in that project, it also corrupts some of those present in the project
