Also having this issue on Xamarin.Mac... Seems to be when it gets the refresh rate.

What version of macOS are you running on?

Apr 13 '21 22:04 jamesmontemagno

The latest MacOS version BigSur. This happens in Ad-Hoc and AppStore build. Debug build is working well.

Apr 18 '21 02:04 tekmun

Hmmm perhaps the linker is doing some stuff....

Can you link skip Xamarin.Essentials and try that.

Started to see the same or a very similar issue.

System.EntryPointNotFoundException
CVDisplayLinkCreateWithCGDisplay assembly:<unknown assembly> type:<unknown type> member:(null)
double CVDisplayLinkInterop.GetRefreshRate(uint display)

Would appreciate a fix or fallback handling for the refresh rate. Crashed on a "MacBookAir8,1 "running macOS Monterey
