By “playground” are you referring to the built-in GraphiQL IDE (/admin/graphiql)? Working fine on my end.

If you enable Dev Mode, you should be able to see the exact error that’s occurring. Or search the latest storage/logs/web-XXXX-XX-XX.log for [web.ERROR] after the error occurs.

Apologies for the late reply, lost track of the issue and wasn't able to pull the logs up until now.
Here are the logs we found:

It looks like you (somehow) have a section that doesn’t have any entry types. Not possible from the control panel, but maybe it could happen from a project config merge conflict or something like that.

The relevant code hasn’t changed in Craft 4, so I’ve made it more defensive for this possibility for the next Craft 3 and 4 releases.

You can test the fix by changing your craftcms/cms requirement in composer.json to "dev-develop as 4.0.4" and running composer update.

[brandonkelly]

Craft 3.7.45 and 4.0.5 are out now with that fix.
