Sorry to hear that... maybe it's a bug? You started new this update, right? I know that playing on old save game on a new version can lead to problems. But itch.io seems to remove the old save games anyway, when I upload a new version.

yes
I can offer to take a look into your save file if you like. If you want that you can contact me on my Discord for details :)
I'm playing version v.34
