It looks like it's downloaded to your OneDrive, so it could be that RenPy wasn't able to load a certain file due to your permissions settings or a connection error.
I wasn't able to replicate this error, but it's also possible that v1.12 wasn't uploaded to / downloaded from Itch fully.
I'll be uploading v1.13 this evening. Try downloading that to your local desktop files and let me know if the issue persists.
