Even though beta 3 change logs claim there's a fix for the preview error Type 'WidgetEntryPointFactory' does not conform to 'NonUIEntryPoint', it is still an issue for me consistently.
The previously accepted workaround for this issue also doesn't work for me anymore, which was: mv ~/Library/Developer/CoreSimulator/Caches/dyld{,_old} ; sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService.
What's a developer to do to get the preview working again? 🤓
Full diagnostics message I get:
RemoteHumanReadableError: Type 'WidgetEntryPointFactory' does not conform to `NonUIEntryPoint` (in framework at path /System/Library/PrivateFrameworks/ChronoCore.framework/Support/WidgetPreviewsExtensionAgent.bundle)
