Hello Rabbani jdce,

Thanks for update. Could you please let us know have you update and clear the Trusted Platform Module (TPM), as suggested in our first response? If not, please check with that option first and to perform such step if you have any difficulties, contact your IT Admin. If you had already did that troubleshoot steps but still issue persist, try to clear Teams cache by the below steps and check the result.

Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.

Go to File Explorer, and type in %appdata%\Microsoft\teams.

Once in the directory, you’ll see a few of the following folders:

From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.: %appdata%\Microsoft\teams\application cache\cache

From within ‘Blob_storage’, delete any files that are located in here if any.: %appdata%\Microsoft\teams\blob_storage

From within ‘Cache’, delete all files.: %appdata%\Microsoft\teams\Cache

From within ‘databases’, delete all files.: %appdata%\Microsoft\teams\databases

From within ‘GPUCache’, delete all files.: %appdata%\Microsoft\teams\GPUcache

From within ‘IndexedDB’, delete the .db file.: %appdata%\Microsoft\teams\IndexedDB

From within ‘Local Storage’, delete all files. : %appdata%\Microsoft\teams\Local Storage

Lastly, from within ‘tmp’, delete any file. : %appdata%\Microsoft\teams\tmp

Once finally done clearing, you can now restart Teams from your local desktop and all cache will be cleared from the desktop app.

Thanks and regards,

Hello Rabbani jdce,

Regarding your issue, have you tried to check if you are able to login Teams online app? If not, please use any InPrivate browser mode and login to Teams web app and check if issue persist or not. Also please share screenshot about the error message. If the same issue occurs on Teams Web app, kindly let us know when this issue start to occurs?

Further based on our knowledge seems this error is related with WAM error, issue may be with account authentication. WAM plug in needs keyset to encrypt tokens for authentication, on Windows, TMP is where saves our keysets. you may try to update and clear the Trusted Platform Module (TPM). Please be kindly**** Clearing and resetting’s **** can result in the loss of data . To avoid data loss, make sure you have a backup or recovery method for any data protected or encrypted by the TPM. If you don’t know how to do it, please contact the IT admins in your organization.

Thanks and regards,
