Crash on iOS 15 EXC_CRASH (SIGKILL)

I received multiple crash report from the Xcode Crashes Organizer.

they all occur on iOS15+ system, I can't figure out why this happen.

Kernel Triage:

No Termination Reason in crash report, and the full crash log is in the attached file. what should I do?

Your crash report is missing the termination info as you noted, which is crucial for this type of crash. Please see a different thread for some action items we'd like you to take when you have a crash report in this state so we can investigate why the termination reasons are missing from your crash report.

Once you've done those items from the other thread, turn your attention to Thread 0 and Thread 7 and third-party SDK it contains. They have the same symbols in the backtrace. Further, the fact that the top frame on the main thread is waiting says this is a watchdog termination and your app's main thread was not responsive, and you should discuss those those conditions with the SDK vendor.
