I have branding and user management, and got the following error

INFO: Launching script to check if a migration is needed ...
Traceback (most recent call last):

Due to incompatibility reasons for this specific version all plugins have been
disabled. Make sure to update your repo index and install the latest version of
your plugins before re-enabling them.

You can use the following commands to upgrade your plugins:
rudder package update
rudder package upgrade-all

I suspect it's because they are not available onthe repo, but i'm unsure of this hypothesis
