Game fails to open with Seamless Coop

[R4ng3x]

Opening the game with the normal launcher works perfectly, but opening it with Seamless Co-op opens the cmd and the game pretends to open but closes instantly.

I am playing on Windows 11 with the game on the latest version and Seamless Co-op on v1.5.1.

Same here with er-patcher and the latest seamless-coop 1.7.6 running on Linux Steam/Proton Experimental

I can confirm this bug. As a temporary workaround you can open the file er-patcher and remove the very last line: rmtree(game_dir_patched)

I will have a look at this and might open a PR if I find a solution.

For debugging I'll leave the error message here:
