Did you make sure you don't have the form opened in another tab/window? This just happened to me yesterday with a SharePoint PowerApps custom form. I went to see all versions and clicked on the one I wanted to restore and got the same error message. Then I realized that when I click on see all versions it opened a new tab. So I just needed to go back to the tab with the open form design and close it.
