Visual Studio is unable to sign in my user into IDE.

Question

I'm unable to sign into visual studio using my @mircosoft account. I've reinstalled visual studio and tried logging in w both Azure VPN and MSFT VPN.

Any reason this would start failing today. How can I fix this so I can log into visual studio? Below is a screenshot of one error message. Other times I can look at error logs files and I see error reported by MSAL.NetCore.4.58.1.10.MsalClientException.

ErrorCode: authentication_ui_failed
```See above error message when trying to login to Visual Studio 2022 v17.10

I've re-installed visual studio and tried logging in from both Azure and MSFT VPNs. Also tried restarting computer and wifi connecition.

Hi @Filmon Belay, 

Welcome to Microsoft Q&A! 

Please close all running Visual Studio instances and manually delete the following account caches folders:

%localappdata%\.Identityservice

%localappdata%\Microsoft\Team Foundation\x.0\Cache  

Then, re-launch the Visual Studio 2022 and sign into your account.  

Sincerely,

Anna

Hi Anna thaks for your respnose,

I've deleted **%localappdata%\.Identityservice**

But don't have **%localappdata%\Microsoft\Team Foundation\x.0\Cache** on my machine.

After removing .Identityservice I'm still unable to run Visual Studio.
