The problem

When firing up a dev container and while running though onboarding and initial setup I received the following error:

When manually entering the shell of the running dev container it seems mutagen is not installed properly:

# pip list | grep mutagen
# 

Manual installation seems to work OK:

# pip install mutagen==1.47.0
