I haven’t been able to reproduce the problem, but I did find one possible problem which is specific to the way UI-based upgrades work. This should take care of it:

[https://github.com/discourse/discourse/pull/34694](https://github.com/discourse/discourse/pull/34694)

It also forces a recompilation, so sites that have already been affected by this bug will be sorted after their next update.
