Abort message: '* Assertion at /__w/1/s/src/mono/mono/component/debugger-agent.c:5521, condition `nfields == 0' not met' #8653
Description
Android application type
.NET Android (net7.0-android, net8.0-android, etc.)
Affected platform version
.NET 8
Description
When working with Maui, we encountered a problem. Sometimes, if you hover the mouse over a variable, the application on Android crashes when trying to evaluate a value with error in logcat: condition 'nfields == 0' not met.

Steps to Reproduce
Unfortunately, I can't provide an example to reproduce, as it doesn't reproduce on a simple application.
As I understand it, the problem occurs on this line in the libmono-component-debugger library:
https://github.com/mono/mono/blob/38b0227c1ce0c53058a5d78d080923435132773a/mono/mini/debugger-agent.c#L5630C2-L5630C11
Perhaps you know how to disable assertion for an application (there is some option in the csproj or you can set some variable with the adb shell)?
Did you find any workaround?
