I can repro this issue at Android platform on the latest 17.11.0 Preview 6.0 (8.0.71 & 8.0.70).

Also here to confirm the issue on the latest MAUI, compiled against net8.0-android34.0.

When debugging the provided MauiSampleApplication solution on Android, I also see output messages about the fonts (not just Maui Material Assets.ttf but also OpenSans-Regular.ttf).

Messages in the output window:
Java.Lang.RuntimeException: Font asset not found /data/user/0/com.companyname.mauisampleapplication/cache/Maui Material Assets.ttf
And:
Java.Lang.RuntimeException: Font asset not found OpenSans-Regular.ttf

But the app just runs and shows the correct fonts.
Also the release version seems to work without crashing.

My issue is, that we are using a 3rd party control (via a nuget package) that uses an embedded font.
Debug works, but the release version crashes (on some Android devices, not all) with the same messages as above, only then as fatal exceptions:
Abort message: '[ERROR] FATAL UNHANDLED EXCEPTION: Java.Lang.RuntimeException: Font asset not found /data/user/0/<ApplicationId>/cache/Maui Material Assets.ttf
and:
Abort message: '[ERROR] FATAL UNHANDLED EXCEPTION: Java.Lang.RuntimeException: Font asset not found OpenSansRegular

So our issue is: using a nuget package that contains an embedded font crashes the release version of the app on some Android devices.
The app starts up correct, but then whenever the fonts are being used, the app crashes.
