I have been having this kind of issue since Friday (5.April) evening (iPad Pro 2018, 12.9-inch, iPadOS 17.4.1).
It all started with the Files app not responding (not showing deleted/updated/downloaded... files), then it propagated to other apps. Every app using iCloud Drive as its base is opening with a blank browser screen (the left-side bar is usually there, but unclickable).
Now Files, PDF Viewer, Numbers, GoodNotes, ..., everything I tried that works with Files opens to a blank screen, nothing else. After a while the app in question crashes. I tried to launch Mail, Safari, Acrobat, ... they all work well and as expected.
I tried to Uninstall the Files app, and then reinstall it. No change.
Force restart or ordinary shut-down, turn-on procedures make the system work for maybe a minute, but not always. Then everything is blocked again. I believe something happened with the outage Apple servers received last week, but my Mac and iPhone are working more than fine.
I believe I will try the following steps, unless someone else has better ideas:
1. deactivate iCloud Drive on iPad. Restart the iPad. See if the apps resume working. If not...
2. log out from Apple ID. Restart the iPad. See if things get back to normality. If not...
3. I'm downloading the Restore image and will try to reinstall iPadOS without Restoring the device. If it doesn't work...
4. Restore the iPad completely. If it doesn't work... I will contact Apple Support.
