[2022] Corrupted save files

Hi,

I encountered a bug that prevented me from progressing in the story. After looking online I tried reinstalling the game. Suddenly all my save games are corrupted. Most of the save games originate before I encountered the bug. Now I can't continue the story and all my custom control settings are gone. Any clue how to fix this? I would hate to have to trow out the game because it was great fun, but if I have to start anew the game will end up in the trash, because there is no way I'm redoing 50+ hours of grinding and leveling.
