Hi Luke
Open Settings and go to Windows Updates > Windows Insider Program and click on Insider Settings.
Send a screenshot of that.
If that screen is blank, tell me which channel you are in (Dev or Beta).
Then, press Windows+R and type winver. Press enter.
Send a screenshot of the window that appears.
While taking the screenshot, make sure you do not capture any personal info like phone numbers, email, IDs, etc.
Regards,
