crash "export reports"

[tntechnology]

The program crashes when I exporting the reports. All reports are written in the document folder, but "open in" does not appear. Is there a problem with the compression as ZIP? I use Xcode 11.4.1 with iPhone 11 and the current version of AppSales 2.4.5 (711).

The following error message appears in the console after the crash:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.' What could be the reason?

Thanks for your help!
