A user gave me the crash log on his M4 machine when he first launches the app. I have M1 and my app works fine, which begs the question, why M4 has the crash! This is my app the I developed since 2011 until now. Any hints will be appreciated or anyone has similar issues like to share?

Is this your code FincancialCoreFrameWork? I ask because "Financial" is spelled incorrectly, and "Framework" is one word not two, so doesn't need the W to be capitalised.

It looks like some error accessing a file? Can you put in some error handling around that?

Also, are you sure this only happens on an M4 Mac? What version of macOS?

Please post the full crash report; see Posting a Crash Report for advice on how to do that.

Also, try to symbolicate your crash report. Specifically, symbolication should reveal a source file and line number for frame 1. That’ll help isolate the issue within your -loadFromContents:ofType:error: method.

For advice on how to symbolicate, see Adding identifiable symbol names to a crash report.
