Ubuntu update window freezes on click of "Install Now" button, doesn't show update progress.

[Lyubomir]

1. The Ubuntu "updates available" window is shown.
2. I click "Install Now"
3. From some time the following has started to be the behavior:
Window freezes, button "Install Now" stays in focused mode, the window doesn't change with the names of the packages being downloaded.
If i "restore down" the window with Super + Down Arrow, it shows the packages that are downloaded as was doing before it started to have these broken issues.

I've switched to Wayland recently, so it might have something to do with this, but i'm not sure.
