Net7.Android - 'SkiaSharp.Views.Android.SKGLSurfaceView': no Java peer type found

[DevronB]

Android application type

Android for .NET (net7.0-android)

Affected platform version

.Net 7.0.102

Description

I'm using Mapsui in my net6-android project and it's been working fine. I recently upgraded to net7-android. Everything works fine after this update as long as I deploy as Debug. but when I build and deploy a Release version the Mapsui constructor crashes with
System.NotSupportedException: Cannot create instance of type 'SkiaSharp.Views.Android.SKGLSurfaceView': no Java peer type found.

Crash occures on:

var mapControl = new MapControl(Context, null);

Steps to Reproduce

Create new 'Android Application' in VS 17.4.4
Add reference to Mapsui library
construct masui MapControl:

var mapControl = new MapControl(Context, null);

Build and deploy to emulator as Debug - it works
Build and deploy to emulator as Release - it crashes

Did you find any workaround?

no, tried adding SkiaSharp reference but didn't help.

I don't think this is the correct repository for this issue.

If you think it's an issue with Mapsui, their repository is here:
https://github.com/Mapsui/Mapsui

If you think it's an issue with SkiaSharp, their repository is here:
https://github.com/mono/SkiaSharp

oh ok, I thought it was more to do with the release build as it's working in debug mode?

I'll log an issue in SkiaSharp
