UE5 (.2.1) Had some problems building to Quest (3) and VR Preview: Solved!

Besides the documentation, this is my config which works finally:

Download via Android Studio (Tools - SDK-Manager)
SDK Platforms (check "Show Package Details"): 
Android 12L -> Android SDK Platform 32, Sources for Android 32, ARM 64 v8a
Android 10 -> Android SDK Platform 29, Sources for Android 29, ARM 64 v8a
SDK Tools (check "Show Package Details"): 
Android SDK Build-Tools 34 -> 32.1.0-rc1, 32.0.0, 29.0.3
NDK -> 25.1.8937393
Android SDK Command-line Tools -> Android SDK Command-line Tools 11.0, 10.0
Android Emulator
Android Emulator Hypervisor Driver
Android SDK Platform Tools

Unreal Engine Project Settings:
Android SDK:
Min SDK: 29
Target SDK: 32
NDK: 25.1.8937393 (26.x doesnt work)
JAVA: JAVA SE 8 (https://www.oracle.com/de/java/technologies/javase/javase8-archive-downloads.html)
SDK API Level: android-32
NDK API Level: android-29

SDK Paths:
Location Android SDK: C:/Users/[Username]/AppData/Local/Android/Sdk
Location Android NDK: C:/Users/[Username]/AppData/Local/Android/Sdk/ndk/25.1.8937393
Location JAVA: C:/Program Files/Java/jdk1.8.0_202

Settet these Paths also in the environment variables ANDROID_HOME, NDKROOT, JAVA_HOME

VR Preview:
I had problems getting the VR Preview to work.
While trying the XR Simulartor, i settet the Environment-Variable "XR_RUNTIME_JSON". Had to remove that, because the path doesnt exist anymore (deleted the MetaXRSimulator-Folder and did not remove this variable)
This tool https://github.com/maluoi/openxr-explorer should show the active runtime (oculus). With the wrong environment-variable, openxr-explorer shows "no runtime settet" or something like that. This tool shows errors, if something is wrong

Start Oculus Link before Unreal Editor
