Unexpected Error while loading libraries / startup

[michaelkargl]

Hey there! Just upgraded to the latest version (pip install portablemc==3.3.0). Unfortunately, the application runs into an unhandled exception on start:

PS C:\Users\Michael\AppData\Roaming\.minecraft> pip uninstall portablemc

That command worked fine in the previous version

PS C:\Users\Michael\AppData\Roaming\.minecraft> pip uninstall portablemc

Is there anything I can do to help?

I'll test this, thank you for the feedback! I was a bit afraid of this happening when adding a hard error on such cases. For know, you can revert, I'll push a fix today.... Definitely lacking tests

[mindstorm38]

Perfect! I can reproduce it

[mindstorm38]

Should work now!

[mindstorm38]

I'll yank the 3.3.0 version.

That was impressingly fast! We just used v3.3.1 in our scripts and it works great. Thanks a lot for the quick fix 🚀 Happy weekend!

Thank you!
