Places app not working on mac

Teams version issue:

Update Teams to the latest version first, then try again.
Check whether Teams is the classic version or the new version, as some apps may not be compatible with the new version.
Teams cache issue:

Exit Teams and delete the cache:

rm -rf ~/Library/Application\ Support/Microsoft/Teams

Restart Teams.

Please try to fix by follow:

Clear Teams Cache:

• Quit Teams completely (right-click the Teams icon in the dock and select Quit or press Command (⌘)-Q).
• Open the Terminal (found in /Applications/Utilities).
• Run these commands one by one:

rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams
rm -rf ~/Library/Containers/com.microsoft.teams2

• Restart Teams and check if the Places app works.

Switch Language Settings:

• Some users have reported that changing the Teams language to English temporarily resolves the issue. You can try switching back to your preferred language after testing.

Test on Teams Web Client:

• Log in to Teams via a web browser and check if the Places app works there. If it does, the issue might be specific to the desktop app.

Update macOS and Teams:

• Ensure your macOS and Teams app are updated to the latest versions.
