PowerApps SharePoint Online form owner has lost access

[Anonymous]

Hi there,

I created a PowerApps form for a SharePoint list many weeks ago using the Customize Forms option on the list. Checking the form today, it seems I don't have access to it anymore. I can't create a new list item, or edit an existing one. When I try any of these options instead of the app I get a screen that says:

This app isn’t opening correctly

It looks like you don’t have access to this app. Ask its owner to share it with you.

When I request access through this screen I get an access request email to my own account.

If I try to open the form using the Customize Forms command, PowerApps studio opens up, it tries to load the form, but I then get an error popup with text similar to the warning above.

I checked my permissions and still have Full Control of the list and the site where it is housed. The only change made to the site between the form working and it stopping working was that I changed the URL of the site.

Any help would be greatly appreciated.

@SeanHenderson Amazing, that worked. I was able to delete the hidden redirect site that had the old URL, and change the URL of the affected site back to this old URL. The PowerApp is working again. I think I'll hold off on trying to change the URL of the site again. But if I do change it and I can successfully reconfigure the SharePoint data source to point to the site with the new URL, I will post my results here. Thanks again for all of your help!
