Hi there! This is Marc. Thank you for reaching out to the community.
Thanks for providing those details. Based on what you've described, here are a few approaches we can try.
Since you've already tried the common fixes, here are a couple more things to try:
Open Command Prompt as an administrator and run this command:
wsreset.exe
This will clear the Store cache and might help fix the loop.
Re-register Microsoft Store: Open PowerShell as an administrator and run:
Get-AppxPackage -allusers *WindowsStore* | Reset-AppxPackage
Ensure your PC’s date and time are set correctly. Incorrect settings can sometimes cause login issues.
Ideally, perform a System File Check (SFC) Open Command Prompt as an administrator. Run the following command to check and repair system files:
sfc /scannow
This will scan and fix any corrupted system files that could be causing the issue.
If all else fails, try creating a new local account and sign in with your Microsoft account there to see if the issue persists.
Let me know how it goes.
Best regards,
