Build fails on iOS physical device - works with simulators

[ShadowOfPhantom]

When I'm trying to deploy an app to my physical device it fails and says "Could not AOT the assembly":

2>C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(254,3): error MT3001: Could not AOT the assembly '/Users/myname/Library/Caches/Xamarin/mtbs/builds/BigVoicy.iOS/457d748bf590932e857801503d02cf86f2a3ac976bb577a9ba10729fa117f5b3/obj/iPhone/Debug/mtouch-cache/3-Build/Plugin.MtAdmob.dll'

It successfully deploys on a simulator but then fails with error: System.TypeLoadException: 'Invalid type MarcTron.Plugin.Services.RewardService for instance field MarcTron.Plugin.MTAdmobImplementation:rewardService' (attached a screenshot)

Is there any ideas how to fix that issue? 🤔
