It seems the behavior you're describing is related to snap and lightdm and not to ubuntu-advantage-tools. And the traceback in the ubuntu-advantage.log seems due to a snap error.
So I'm going to assign this to the snap and lightdm packages, and I'll mark it Invalid for ubuntu-advantage-tools. Feel free to change the status if you discover it is a bug in the ubuntu-advantage-tools package.
As an aside: It appears you have jammy-proposed enabled, which generally isn't recommended for normal use and may be unstable. I can tell because ubuntu-advantage-tools 27.11.3~22.04.1 is still in -proposed and hasn't been released to -updates yet.
Thank you for reporting this bug!
