Xamarin Stuck Building Archive - xamarin.forms

Question

When building my Xamarin project, it gets to this part of the build process and hangs forever. Left it overnight only to find it sitting in the same spot in the morning.
[aot-compiler stdout] Executing the native assembler: "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Xamarin\Android
dk\aarch64-linux-android-as" -o obj\Release\110\aot\arm64-v8a\Xamarin.Forms.Core.dll\temp.s.o obj\Release\110\aot\arm64-v8a\Xamarin.Forms.Core.dll\temp.s
[aot-compiler stdout] Executing the native linker: "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Xamarin\Android
dk\aarch64-linux-android-ld" -Bsymbolic -shared -o obj\Release\110\aot\arm64-v8a\libaot-Xamarin.Forms.Core.dll.so.tmp obj\Release\110\aot\arm64-v8a\Xamarin.Forms.Core.dll\temp.s.o
[aot-compiler stdout] JIT time: 139 ms, Generation time: 1707 ms, Assembly+Link time: 612 ms.
Is there somewhere else I can look to see if there are actual errors occurring, which might be causing the issue? App will run on emulator fine in Debug mode, but this happens when building in Release.
Note, that on occasion I can get it to complete, but not consistently.
In Archive Manager, the green bar just keeps scrolling, showing "packaging" of the app.
These are the configurations of the two builds:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
<DebugSymbols>true</DebugSymbols>
<DebugType>portable</DebugType>
<Optimize>false</Optimize>
<OutputPath>bin\Debug</OutputPath>
<DefineConstants>DEBUG;</DefineConstants>
<ErrorReport>prompt</ErrorReport>
<WarningLevel>4</WarningLevel>
<AndroidLinkMode>None</AndroidLinkMode>

</PropertyGroup>
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">

<AndroidCreatePackagePerAbi>false</AndroidCreatePackagePerAbi>
<AndroidLinkTool>r8</AndroidLinkTool>
<EmbedAssembliesIntoApk>true</EmbedAssembliesIntoApk>
<AndroidKeyStore>false</AndroidKeyStore>
</PropertyGroup>
Is it possibly an R8 issue?
