[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] yaazzz:
I think I break some file after installing a module with Magisk :(

I can not remove the modules that I suspect to stop the boot as I do not have root access anymore :( here is the extract of errors inside of the logcat during boot :

Can someone post his /vendor/etc/audio/audio_effects.xml for comparaison?

My apology if you judge it off topic.
