Hello, I get this error many times. It is triggered in many ways, right now it was by changing renderer. What cause this error? Am I doing something wrong?

And now this one error:

While I add in Material graph “pow” function to color output of the texture.
Thank you for your post. Does this happen a lot with any scene or just one in particular ? If it is one scene, please zip it up and attach it. If it is across multiple scenes it may be a hardware problem. Next time it happens, please send your LOGS as soon as it crashes so we can analyze.
Thanks
Richard
I think only on that specific scene, but I am not able to ZIP it and attach it. Yes its across multiple scenes.
