I have been experiencing this issue since February and it still has not been fixed. Whenever you manually insert “DX12” into the Xbox game file TSW4 will still run in DX11. This has caused crashes on all core routes, there are even crashes on DLC which do work on previous TSWs. Edit: It’s only an issue on Xbox as with Steam TSW inputting DX12 will allow me to run the game on my PC.
Are you editing the Xbox game file(s) as in the save game, or are you doing it on the PC after downloading the Xbox content to the PC with Win11, I did not think you could do that.
