I always get this error when trying to show a preview since yesterday after updating to Xcode 14.2.
Before that update, previews in Xcode 14.1 worked fine.
Now I always get this error...
I quit and relaunched Xcode several times. I trashed Xcode, downloaded a new copy from Apple Developer, same result.
I deleted the Simulator "iPhone 14 Pro" and created a new one. Same result...

Playgrounds 4.1 always crashes a few seconds after launch without even showing a window. When I switch to my Admin user, it doesn't crash. I can run simple Swift code there.
My daily user account (where it crashes) doesn't have admin rights.
rMBP late 2016 (won't get macOS 13) with macOS 12.6.1 (fresh installation 2 months ago without Migration Assistant, so no old prefs and stuff). Playgrounds 4.2 requires macOS 13.
I deleted all playgrounds files from iCloud. Still crashes...
Any prefs which I could delete?
