===========Happened when I was switching from Object to Edit mode. First time and unexpected as never a problem before. I suspect prior switching the views from EEVEE then Radeon ProRender and finally Cycles made this happen. I have actually had very few crashes despite all the anomalies I get daily using a non-CUDA GPU. So good luck with this and I wouldn't spend too much time on it unless others are having the same crash.
