Hi @Иван русанов,
Welcome to Microsoft Q&A!
Please navigate to the path: C:\Users\<Username>\AppData\Local\.IdentityService. And check if the VBAccountStore.lock and V3AccountStore.lock files exist and ensure that you have full control to the location.
If it exists, please backup and delete the VBAccountStore.lock and V3AccountStore.lock files. Then, go to Visual Studio Installer > More > Repair the Visual Studio > re-launch the Visual Studio.
If it doesn’t work, you can manually delete the %localappdata%\.Identityservice folder (C:\Users\<Username>\AppData\Local\.IdentityService) and try again.
Sincerely,
Anna
