Does this happen specifically within your app? Does it happen with a new MAUI UI Template app? Does it happen on a dotnet Android (dotnet new android) app that doesn't use MAUI UI?

[mfeingol]

@drasticactions: clean new sample app seems to work with LLVM enabled.

Verified this original issue with Visual Studio 17.11.0 Preview 2.0 (8.0.60 & 8.0.3 ). Cannot repro it on android

[mfeingol]

I installed VS 17.11.0 Preview 2.0. Was able to repro with 8.0.60. Attempted to install 9.0.0-preview.5.24307.10 and had a bunch of unresolved resources and namespaces when compiling for Android... which I didn't have time to work through so I gave up on that.

tldr, it still repros with the latest VS preview.

[PureWeen]

@jonathanpeppers any thoughts?

[jonathanpeppers]

I think we can move this to runtime.

@mfeingol you might see if you can get a more detailed log with:

# clear the log
adb logcat -c
# enable more logging
adb shell setprop debug.mono.log default,assembly,mono_log_level=debug,mono_log_mask=all
# make the app crash
# save the log (share it here)
adb logcat -d > log.txt

Later, when you want to disable the logging, call adb shell setprop debug.mono.log "''" or reboot the device.

[steveisok]

@mfeingol can you please provide a repro and logs (if possible) so that we can investigate further?

[mfeingol]

@jonathanpeppers, @steveisok: sorry for the delay. Here's a log of the crash:

log.txt

If you need a repro, I can grant you access to my project.
