When running app on an iOS 13.x device I get the following error: modifications-to-the-layout-engine-must-not-be-performed-from-a-background-thread. The same app with no modifications Works just fine on iOS 12.

This has to do with exportData.saveAndShare(base64Data, xlsFileName, gCurrentEventname, this.saveAndShareCallBack); Any information on how to resolve this would be appreciated.

If you are making any UI changes in the callback then, you need to run the callback on the main thread. Any kind of UI changes should happen only on the main thread only. Please check the below doc to execute the callback on main thread.
