Some issues with Teams can be resolved by clearing the cache for the Teams app. Microsoft support has some instructions here on how to clear your Teams cache: https://learn.microsoft.com/en-us/microsoftteams/troubleshoot/teams-administration/clear-teams-cache
I will reiterate them below as well.
For Windows:
- If Teams is still running, right-click the Teams icon in the taskbar, and then select Quit.
- Open the Run dialog box by pressing the Windows logo key +R.
- In the Run dialog box, enter %appdata%\Microsoft\Teams, and then select OK.
- Delete all files and folders in the %appdata%\Microsoft\Teams directory.
- Restart Teams.
For Mac:
If Teams is still running, right-click the Teams icon in the dock, and then select Quit, or press Command (⌘)-Q.
- Select the magnifying glass in the upper right corner, type in "Terminal", and press Return.
- Enter the following command, and then press Return: rm -r ~/Library/Application\ Support/Microsoft/Teams
- Restart Teams
