Microsoft Teams Error 80090016 "Your computer's trusted platform module has malfunctioned"

Question

Whenever I try to login to Teams I get this error, and it's really weird because once I was able to login but all my chats disappeared and I wasn't in the team I'm supposed to be. Teams used to work just fine on my computer until yesterday after I had to unplug my HDD and plug it back in (which shouldn't matter since teams is on my SSD). I have already tried clearing TPM on both windows and bios, deleting everything inside the NFC folder, disabling ADAL on the registry, rebooting, reinstalling Teams and some more. I can normally add the account to my windows accounts and use it on Outlook, but Teams just doesn't like it. Another weird thing is that in Chrome I can't access teams browser version (stuck on loading screen infinitely) but I can just fine in Edge. Teams mobile on my phone also works, I have no clue what's going on.

Edit: I don't know how but I managed to finally login. I don't know what caused it to work but I removed and readded my account to windows, uninstalled Office, tried again when I got the error on teams and logged in and all of a sudden it worked. If anyone has any idea of what could be the problem please answer in case it happens with someone else or again with me.

Hello Volks,

Problem solved; but not with the above Solution.

Here is what worked for me:

in Short: Solution for me is to delete this Folder:

C:\users<user>\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

(this Folder is generated new when you logon again...)

but nevertheless i had a strange behavior:

When i logged on for the first time after deleting the above mentioned folder a WINDOWS Question asks if

my Organisation can handle my (Windows)"Machine" with Button <OK> 

or with a small  Link Text: "No only want to login to this App".

If i hit the Button <OK> then i had the same Error Code 80090016... :-(

Second Try i hit the Link Text: "No only want to login to this App" and then

Windows is initializing the Teams-Window and Starts the App :-|

Great MS...

Dear Ankita Vaidya,

Please, write a step-by-step method for the solution, because not everyone understands your topic, like me. I have the same problem with Teams, cannot log in, my son is online school, so this is a big issue!

Dear MThano,

I did what you advised, and it worked, problem solved. Many thanks for your smart advice.

One thing. When you are deleting the folder, you might have to do it folder by folder, but this really works.
