I also have a 5700XT and was experiencing the fatal error 100000000 any time I tried to start the game in DirectX11. Currently running Windows 11 with a 5900X. AMD 21.9.2 driver. This is what I did to fix the problem today. In the settings for scaling mode "Full Panel". After that, finally got the game to run in DirectX11 mode. Now, there are other issues with fatal errors that can pop up but most of what I've seen dealt with audio and having to specify output and disabling enhancements. Hope this hepls.
