Thanks for the report @1work1Tester, we've identified the issue and created PR #2051 to fix it.

Until we release a new version to PyPI you can probably apply the patch manually and then delete the mu/wheels/1.1.0b7.zip to force Mu to download the venv dependencies again.

A new version with this fix has been released to PyPI 🎉 https://pypi.org/project/mu-editor/1.1.1/

You can be install it via pip and it should now work :)
