Additional features, settings, or issues not covered by specific Microsoft Teams categories
Andrea Giraldo Ramirez's post should be the first answer....
I did a full drive search and deleted all com.microsoft.teams files. No help.
I wiped the drive of teams files one more time and logged in with Google Chrome.
Next Teams was loaded using a new invite link from the MacBook Pro that was working.
I then logged out of Chrome and it worked.
One note. I use three different computers every day, and log into all three. I was logged out in order to make this happen. There is a possibility although very remote that being logged in on more that one location might not help.
Best of luck and I hope it keeps working.
