I’ve just installed Unreal engine 4.27.2 and create a blank game for Oculus quest 2.
After compile shaders, my game cannot launch.

Here is two errors on Output log.

I found the cause. It is missing dx.bat and some other files. They are shipped with ‘Build-tool 32.1.0 rc1’ of Android SDK but their name was changed to from ‘DX’ to ‘D8’.

My solution is rename them to ‘DX’
