Thanks to person who posted the answer on this post. I’m reposting it here in case it disappears.

This is most likely a symptom of bigger problem with your TPM. This is a band-aid that will get you back going until you can figure out a long term fix.

Delete certificates

Open the certificates console by going to Start > Run > mmc

mmc

Click File > Add/Remove Snap-in…

Select Certificates and click Add

Select Computer account then Local computer. Then OK

Open Certificates > Personal > Certificates
Delete any certs that contain MS-Organization in the name

Delete Teams cache

You could delete any data that has not been synced to Microsoft’s servers. Please log into the web versions of Teams to verify everything is up to date before deleting your local cache.

Open %appdata%\Microsoft\ and delete the Teams directory

%appdata%\Microsoft\

Uninstall teams

appwiz.cpl

Download and reinstall Teams
