First, check that you’ve waited long enough for everything to start, and that you don’t have some kind of browser cacheing getting in the way.
But, it can happen that a second rebuild will do the trick, so that’s worth a try.

I think a git pull can help too:
cd /var/discourse
git pull
./launcher rebuild app

When you “disabled”, what does that refer to? Do you mean the buttons on the upgrade page are not clickable?
Could it be there are no upgrades to be had?

The experimental aarch64 image arch is indeed failing to automatically pull in the last image during rebuilds, it’s on my list to investigate why next week.
