Are you trying to play D3 or D2R?
This is the D3 forum. The most common cause of D3 crash on start is Razer software. You can read about that here Known Technical Support Issues - [Updated June 21, 2020!] - #3 by Zuvykree
Other overlays can do it too.
If your issue is with D2R then it would be because you have an integrated graphics card and those are not supported as far as I know. They did not work in Beta.
