I need help with my TestFlight crash report. I have already symbolicated my crash report but I don't see an error.

My application always crashes at the same position when I open it on my iPad Air. It doesn't crash in debug mode which makes it very difficult for me to find the issue.

My crash report from TestFlight:

Then I symbolicated all the lines starting with "ProjectiOS" in my crash report but I cannot find the issue. Which lines in my crash report cause the crash?

Thank you for the crash file. However, it appears that the crash file is not symbolicated from your symbol file. The crash occurred in thread 0, but there are 16 frames for the project ProjectiOS without symbols.

Kindly submit a comprehensive crash report, adhering to the guidelines outlined in Posting a Crash Report.

I uploaded a new version to TestFlight and here is my symbolicated crash report. My application always crashes shortly after launch. Can my symbolicated crash report help to find the issue?
