Hi @Alan Hawkins,
Welcome to Microsoft Q&A!
When I open vs15 in win11, it says “License: Prerelease Software , Your license has expired.
It shows that your license has expired. Please click on “Check for an updated license” to refresh the license.
If it doesn’t work, please sign out and sign into a new account.
Besides, please ensure that the VS is the latest version and try to repair it.
Sincerely,
Anna
