Error when filling out password and cannot close pop-up

I was in the process of ordering a new sim card for a phone from the website https://spusu.at
During the process, I wanted to use the "generate password" function to generate a password for the site.

It showed the password normally, but when I clicked on it, a popup said "Password could not be filled" (translated on the fly since my extension is in German). I tried it again 3 more times, and the fourth time, it worked and the password was filled out.

However, I am now unable to close the popup that states "Password could not be filled". Clicking on the "X" does nothing. Inspecting the browser console, I see that there are a few errors. 1 is related to the "close popup" having an error, and the others seem related to not having the desktop app installed.

I have the extension installed on this computer but not the desktop app (it's a work laptop which restricts installed apps).

This error is not a big deal for me, since the autofill worked after a while and the popup will go away when I reload (hopefully). I just wanted to report this error.
