Answer 1

Hello,

Got a SIGSEGV while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application.

Usually, this error message is caused by asynchronous tasks.

You could try to troubleshoot from the relevant code comments in the Task, Thread, and timer parts used in the project.

Best Regards,

Alec Liu.
