I have an issue, where my save file was corrupted and simply gives me the error message "Cannot read property 'length' of undefined". It is only my newest save that has been corrupted in this way, so I would only lose ~3 hours of progress, though, I would rather not lose any progress if a possible fix exists? The save is from 25/09/23.
I got it to work, thanks for the help. It seems to have been a problem of my installed game files, which only affected the newest save file for some reason. Completely deleting and reinstalling the game in the newest version worked (Which I tried after a new install of an older version also worked.).
