Not sure, but those artifacts are an indication of video cards driver problems.
Are you using Eevee or Cycles?
Are you using a laptop?
Looks like graphics card problem AMD issue. Often links to Eevee.
Yes i use the laptop and eevee. I need do something with my drivers? Or the only way is use cycles instead?
Today all is ok, maybe it needed reboot blender or laptop
The old turn it off and back on again technical fix.
I’m glad it worked out!
Have fun, show your work!
