Can't login to fresh installation of Microsoft Teams

I can't login to Microsoft Teams app on my laptop. It's newly installed on my machine.
 

When it opens I get asked for my email address and then it gives me the error number 0x80190001 with no other information.

 

I have added Teams to my firewall. I'm using TinyWall and I added the process and it TinyWall find the Teams.exe to add. This is better than before because before I add Teams to my TinyWall things were even worse and Teams wouldn't even ask me for my email address.

 

I'm also using Windows Defender Firewall. Even if I switch off my firewalls I still get the same error.

 

I can't find any useful information on any website.

 

I can't see how to delete any log in data for Teams.

 

I can't think of any thing plan of action.

 

Does anyone have any idea what I could try?

 

I have Windows 10 and a new installation of Microsoft Teams.

    I have the same problem with the new teams and tinywall. I can't connect anymore to teams unless i turn off the firewall.

    Unaccecptable from micvrosoft to let users in that situation.

      To let MS Teams through the TinyWall, you gotta unblock not only the exe file of MS Teams, but also the WebEdgeService. Just right click the TinyWall icon at the bottom right corner and select Whitelist through window. Then doubleclick MS Teams and it should show you, that it unblocked both. If not, do it twice.
