Both appcenter.ms and Apple symbolicatecrash cannot find the referenced mono.dSYM in
0x105464000 - 0x1056cbfff Mono arm64 <bfbc7c55b8243c049ad6028b16bf2eb9> /private/var/containers/Bundle/Application/1C0150F5-648F-429F-B3B2-69E3ABDBF0F5/apdl.app/Frameworks/Mono.framework/Mono
Two questions
1) Can I symbolicate the following crash in Mono ?
2) Are the dSYM for ARM64 available for Mono.framework/Mono ?
Bonus Question
3) Any ideas of why the thread during spinup is crashing

As far as a known, dSYM for ARM64 is available for Mono, this are 32/64-bit platform considerations.
You could find the .dSYM file, refer to
