Did you try verifying local files for the game?
Items stats are saved with the game, so either the crash corrupted all your saves somehow, or something in the game is overriding or preventing the saves from being read properly.
Please email supportdos@larian.com, with a description of the problem and the report.zip file generated by the
D:OS support tool. The zip file will include your saves, so hopefully Larian can figure out what the problem is.
