Description
We first noticed this here:
Release builds (using Mono AOT by default) fail with:
Microsoft.Android.Sdk.Aot.targets(123,5): error : Precompiling failed for C:\a\_work\1\a\TestRelease\05-12_05.25.35\temp\CheckMonoComponentsMaskTrueFalseFalse4\obj\Release\android-arm\linked\System.Private.Uri.dll with exit code 57005.

Reproduction Steps
Likely as simple as:
dotnet new androiddotnet build -c Release
Expected behavior
Mono AOT compiler succeeds.
Actual behavior
Mono AOT compiler fails on System.Private.Uri.dll.
Regression?
Yes, should be something recent in dotnet/runtime/main.
Known Workarounds
You could set $(RunAOTCompilation=false), but most customers would require this for decent startup times on Android.
Configuration
.NET SDK version (vmr): 10.0.0-preview.5.25260.104
