A major error in the game console caused a crash.

There's nothing that can be done here about that. There are alternatives available which you can use.

The reason I filed a report is that none of the versions I found worked.

It's not something that can be solved here. The reason Configuration Manager isn't working with that game is due to IMGUI features being stripped by the game. Configuration Manager relies on those features to render its menu and can't work without them, so it likely won't be solved here.

The one I linked uses a different technique for rendering and works on the Steam build of the game if you follow its instructions. If it doesn't for you, reach out to its author. None currently work on the Game Pass build of the game.

Alternatively, learn to edit configuration files manually. It's not hard: just navigate to the BepInEx/config folder and edit the relevant .cfg file in a text editor.
