Sorry for the problem but this is the "hotfix" version for the May release. Exactly the same one that Patreon got earlier. There could be issues that we didn't know about. If possible can you send us your log file and your backup cache for further analysis?
For now my suggestion is to use 1.3.0 and your backup cache until we figure out what's wrong.
The 1.3.2 released yesterday on Patreon doesn't have any futher library fix than this "hotfix", so it is likely to fail also in this case. Once we receive your files and confirm the root cause we can put the fix in 1.3.2hotfix and release that early in Itch.io.
Also one thing you can try is to check if you have files in your library that has non-english names, sometimes they can cause issues. If there is, you can try rename them and see if the problem goes away. Let us know the result and either way we'll make changes from our end to ensure that doesn't happen again.
Thank you for your understanding.
