I think the dates there are wrong, if you check https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1990450/comments/61 for example, the 1:22.04.16 upload was accepted in proposed on October 6th

Right, so the issue there is happening if update-manager is updated while the interface is loaded.

It's easy to reproduce with those steps
- start update-manager on a newly installer jammy system (1:22.04.10 was installed)
- go to a commandline and install the new update-manager
- in the update-manager interface, clicking on the settings button -> software-properties opens -> close software-properties

it makes update-manager try to reload part of the .ui but the file on disk changed and doesn't match the active binary anymore.
(it could be that simply installing the new update-manager by applying the updates from the GUI is enough to trigger the situation but it's a bit more difficult to test now since the phase was set to 0% so update-manager isn't going to include the package for upgrade)

Technically that isn't really a bug in the new version, another side effect of doing upgrades in a session while it's in use... unsure if there is any easy workaround we could use there.

The error reports state the bug impact the new version because they collect the installed version information at the time where the problem occurs.
