Cant pop out meetings from teams chat
UPDATE!
I figured out a work-around. I have to use an older version of Teams, specifically version 1.5.00.8070 from April 2022. Older versions are available on uptodown.com:
https://microsoft-teams.en.uptodown.com/windows/download/4594768
I tried several newer versions as well, but that was the most recent version in which the pop-out screen-shared content works for me.
The main trick now will be to prevent Teams from auto-updating because apparently there is no in-built way to disable auto-updates. Based on my readings of how the updates are fetched, it might be possible to do this with a static DNS host entry for statics.teams.microsoft.com in the C:\Windows\System32\drivers\etc\hosts file, which points to a dummy address that will not respond (e.g. 127.0.0.1). Possibly also restricting write and/or execute permissions to the directory where updates are downloaded to...

Another update, re: preventing auto-updates:
It seems that the static DNS host entry for statics.teams.microsoft.com didn't prevent auto-update. There must be a secondary url it is using, or maybe the ip address (or an outside DNS server) is hardcoded... dunno.
However, if I restricted permissions to the folder C:\Users\<username>\AppData\Local\Microsoft\Teams\packages , to only read and list folder contents for all profiles, it prevented updates from being installed. (Note that if you only allow 'list folder contents' Teams wouldn't start. You have to allow 'read')
