Build Errors when Compiling for Android

Unity Version: 2020.3.15f2 (LTS) Mirror Version: v44.0.2 (latest) EpicOnlineTransport Version: v1.5.0 (latest) JDK Version: OpenJDK 1.8.0_152 (installed with Unity) Gradle Version: 4.0.1 (?) (installed with Unity) Android SDK/NDK/Build Tools Version: Unknown (installed with Unity) OS Version: Windows 10 Home 21H1, Build 19043.1110, Windows Feature Experience Pack 120.2212.3530

I cannot get a blank Android project to build. Building for Windows works without issue.

Steps to Reproduce:

Create a blank 2D Unity project
Import entire EpicOnlineTransport.unitypackage
Import entire Mirror package from Package Manager
Switch platform to Android in Build Settings
Attempt Build

Notice the following errors:

Found plugins with same names and architectures, Assets/Mirror/Runtime/Transport/EpicOnlineTransport/EOSSDK/Android/libs/armeabi-v7a/libEOSSDK.so () and Assets/Mirror/Runtime/Transport/EpicOnlineTransport/EOSSDK/Android/libs/arm64-v8a/libEOSSDK.so (). Assign different architectures or delete the duplicate.
UnityEditor.AndroidPluginImporterExtension:CheckFileCollisions (string)
UnityEditorInternal.PluginsHelper:CheckFileCollisions (UnityEditor.BuildTarget)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Plugins colliding with each other.

Build completed with a result of 'Failed' in 10 seconds (10174 ms)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

UnityEditor.BuildPlayerWindow+BuildMethodException: 2 errors

Fix build errors by changing CPU in the Import Settings of Assets\Mirror\Runtime\Transport\EpicOnlineTransport\EOSSDK\Android\libs\arm64-v8a\libEOSSDK.so to ARM64

Observe that the build fails again with different errors:
