Hi MWL88
To resolve the issue, please follow these steps:

Clear your browser cache and try reopening the Azure portal.

If that doesn't work, attempt to access the portal using a different browser.

If you still encounter problems, sign out of your Azure account and then sign back in.

These steps should help. If you continue to face issues, please let us know so we can investigate further in our environment.
