iOS 14: Application is crashing when deploying to real device

Hello,

Using:

• VS for mac v8.7.8 (build 4)
• Xamarin.iOS 14.0.0.0

Same code as with previous version (latest Xamarin.iOS 13.xyz before stable upgrade). I cannot deploy anymore my XF project on a iOS 14 iPhone. It works properly with an Android device, an Android emulator and an iOS emulator, but it crashes right after showing the splash/loading screen with:

Sorry, tried many times to copy/paste content but the dialog auto-closes quite quickly not letting me time to click, select and copy to clipboard and I don't know where to gather those logs either. Xcode sees no logs on my device.

Any idea? I was running Xamarin.Forms v4.6-something and tried to upgrade to 4.8.0.1451 but the crash is the same.
