Someone in the russian forum (4pda) shared this patched boot from january ota
I flashed it and the device booted correctly without facing any problem, now magisk works again

you should unlock bootloader first and enable camera2 api
I'm now on https://f.celsoazevedo.com/file/gcamera/MGC_6.1.021_BSG_Arnova-based_v.1.2_TlnNeun_Fix.apk looks like it's fine until this moment
P.S. how do you block update notifications?
I presume it wont be possible or probably available to update oreo with fixes? are those even in work or automatically stop after pie release?
Just enable developer mode and disable automatic updat...
For those who want a temporary solution for the recording issue, just install this app it works well ;)
I'm using viper4android fx (magisk module) it really does the job
