I had the same login issue with MS Team desktop client.

The only solution for me is to run it in compatibility mode:

– right click MS Teams app icon and open the ‘Properties’ window.

– under ‘Compatibility’ tab, check the ‘Run this program in compatibility mode for:’ and select Windows 8

– click Apply and Click OK

Hope this can help you.

For such an issue, you can first try to clear Teams cache in your PC to see if it helps for your dilemma:

1) Fully exit the Microsoft Teams desktop client.
2) Go to File Explorer, and type in %appdata%\Microsoft\teams.
3) Once in the directory, you’ll see a few of the following folders:

a. From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.
   *   %appdata%\Microsoft\teams\application cache\cache
b. From within ‘Blob_storage’, delete any files that are located in here if any.
   *   %appdata%\Microsoft\teams\blob_storage
c. From within ‘Cache’, delete all files.
   *   %appdata%\Microsoft\teams\Cache
d. From within ‘databases’, delete all files.
   *   %appdata%\Microsoft\teams\databases

Basically, this means that you will delete all Microsoft Teams temporary files stored on your machine. Here are the steps to follow:

1. Close the Microsoft Teams client on your desktop
2. Open File Explorer

To quickly access the Application Cache , you can also type

1. %appdata%\Microsoft\teams\application cache\cache

2. in File Explorer

• Go to folder Blob_storage and delete all the files you find in that folder
  Again, you can directly access the Blob_storage folder by typing

%appdata%\Microsoft\teams\blob_storage

in File Explorer.

• Go to Blob_storage folder(%appdata%\Microsoft\team\databases) and do the same
• Open folder GPUCache (%appdata%\Microsoft\team\GPUcache) and delete all files
• Now go to  folder IndexedDB (%appdata%\Microsoft\team\IndexedDB) and just delete the .db file
• Next, navigate to Local Storage (%appdata%\Microsoft\team\Local Storage) and delete all files stored in the respective folder

To work around this issue, remove all 4 JSON files along with the log files from %appdata%\Microsoft\teams

Relaunch Teams to automatically regenerate the JSON files you just deleted. Check if you still have problems logging into Teams after doing that.
