This is the wrong forum for D2R.
This forum is for Classic Games Tech Support… games such as Diablo II (2000).
Diablo II: Resurrected has its own forums here:
There is some troubleshooting for your crashes that you can attempt here:
If that does not solve the issues, please post on the D2R Technical Support forum. You can also contact Blizzard Support by doing a web ticket; click the Contact Us button here to start the process: https://us.battle.net/support/en/help/product/d2r/1935/1937/solution (I am providing the
us.battle.net link since your BattleTag indicates that you are from the Americas region).
Best of luck with this.
