We noticed this past week that the lists on all of our Power Page sites are showing the error below. We noticed that it is using the modern version and we can still select a list, but then after navigating elsewhere, it shows the error message again. The actual preview of the site is still working as expected. We have already tried purging cache, restarting the site, and then creating a new blank site on the environment. I have a support ticket open with Microsoft, but no success yet.
