pjsua2 complied for Mac Catalyst Arm64 being used in C# Maui project throws exception Making call about pjproject HOT 8 OPEN

Try without C#, and try with our sample app.

When I test here and open our sample app and then run it for "My Mac (Designed for iPad)" (which should be equivalent to Mac Catalyst, please correct me if I'm wrong), it works fine. My Mac is M1 ARM64.

Thanks for getting back to me.

apples documentation says OSStatus -10863 = kAudioUnitErr_CannotDoInCurrentContext

Not sure if it helps, but I followed iOS build instruction to successfully run PJSIP on Mac Catalyst on Mac M1 arm64.
