Game no longer launches after The Bugs Strike Back update [linux+proton]

[elliott_fields69]

I know the Grounded devs don't support linux, but wondering if anyone might know what has broken proton compatibility with the new update. Info could be useful for proton devs.

Thanks!!

У меня тоже. Перестала запускаться после обновления. При запуске появляется черный экран с надписью "загрузка" и через несколько секунд игра вылетает на рабочий стол без каких-либо ошибок. Проверял файлы, обновлял драйвера, переустанавливал игру. Стим, Виндовс 10.

I am having this issue as well. Bug report on steams proton github is here https://github.com/ValveSoftware/Proton/issues/4102#issuecomment-1133888246

The error is as follows

[0522/091018.734:ERROR:mf_helpers.cc(12)] Error in dxva_video_decode_accelerator_win.cc on line 355

Unhandled Exception:

I know Linux is not supported but if you could provide any insight into the issue in the comments of the Proton issue tracker for Grounded, that would be greatly appreciated. Alternatively, if changes can be made in an update to the game, could you catch this exception and allow this subsystem to remain unloaded for systems that do not support Microsoft's speech synthesis engine?
