can't symbolicate the crash report. The drag and drop functions doesn't work. https://developer.apple.com/documentation/xcode-release-notes/xcode-13_1-release-notes#Debugging https://developer.apple.com/forums/thread/691407 my report says "exception" : {"codes":"0x0000000000000000, 0x0000000000000000","rawCodes":[0,0],"type":"EXC_CRASH","signal":"SIGABRT"}, "ktriageinfo" : "VM - Fault hit memory shortage\nVM - Fault hit memory shortage\nVM - Fault hit memory shortage\nVM - Fault hit memory shortage\nVM - Fault hit memory shortage\n", I think the new watchdog of ios aborts the app, because the CPU or memory usage? I can't wait to get this fixed. Thank you all. crashlog-0A1C1D33-FA82-4437-85F7-D1F35E428EDC.crash
