Simulator logs,, CoreSimulator logs etc are all empty. There are no useful logs to post, as far as I can tell. Even with debugger, it crashes somewhere inside the exportAsynchronously function. Nothing useful comes from trying to step into it with the debugger either.

I am not getting any stack trace when the crash occurs. I only get a dump from the thread, which appears to be assembly or some instruction set. I'll paste that in full here. libxpc.dylib`_xpc_api_misuse: 0x111774af4 <+0>: pushq %rbp 0x111774af5 <+1>: movq %rsp, %rbp 0x111774af8 <+4>: pushq %rbx 0x111774af9 <+5>: subq $0xa8, %rsp 0x111774b00 <+12>: movq %rdi, %rcx 0x111774b03 <+15>: movaps 0xd9f6(%rip), %xmm0 ; __xpcVersionNumber + 16 0x111774b0a <+22>: leaq -0xb0(%rbp), %rbx 0x111774b11 <+29>: movaps %xmm0, 0x90(%rbx) 0x111774b18 <+36>: movaps %xmm0, 0x80(%rbx) 0x111774b1f <+43>: movaps %xmm0, 0x70(%rbx) 0x111774b23 <+47>: movaps %xmm0, 0x60(%rbx) 0x111774b27 <+51>: movaps %xmm0, 0x50(%rbx) 0x111774b2b <+55>: movaps %xmm0, 0x40(%rbx) 0x111774b2f <+59>: movaps %xmm0, 0x30(%rbx) 0x111774b33 <+63>: movaps %xmm0, 0x20(%rbx) 0x111774b37 <+67>: movaps %xmm0, 0x10(%rbx) 0x111774b3b <+71>: movaps %xmm0, (%rbx) 0x111774b3e <+74>: leaq 0x11303(%rip), %rdx ; "XPC API Misuse: %s" 0x111774b45 <+81>: movl $0xa0, %esi 0x111774b4a <+86>: movq %rbx, %rdi 0x111774b4d <+89>: xorl %eax, %eax 0x111774b4f <+91>: callq 0x1117818dc ; symbol stub for: snprintf 0x111774b54 <+96>: movq %rbx, 0x2196d(%rip) ; gCRAnnotations + 8 0x111774b5b <+103>: leaq 0x112f9(%rip), %rax ; "API Misuse" 0x111774b62 <+110>: movq %rax, 0x21967(%rip) ; gCRAnnotations + 16 -> 0x111774b69 <+117>: ud2

and happening in xcode 12.5

happening in xcode 13.1 as well

Just started seeing this today on Xcode 13 on Simulator, and tested on iOS 15 and 14.5 (both on Simulator). Cannot reproduce on device. This is super frustrating. Anyone have a solve for it yet.
