Catalina 15.4 - STUCK before installer... MGAMING Z390

Hi,

i'm trying to install Catalina 15.4 on a MGAMING Z390.
I've got the i5 9th gen, and went through through Vanilla Clover (clover r5122)

setting up i added the kexts needed and tried to set up the config.plist as good as my knowledge allowed me to.

I always get stuck during the process before reaching to the Mac installer.

Either i endlessly stay at the Apple logo, either the -v showed me that i stoppeed on :

EB|LD:OFS] Err(0xE @ GV wake-failure

xxxx

EB|LD:OFS] Err(0xE @ WL:PWWLFRTC

[EB|LD:OFS] Err(0xE @ OPen (System/Library/PrelinkedKernels/

​

After 2 days stuck there & I still can't get my EFI right nor get to the installer.

I've tried a lot of methods and it growed a sense of despair...

this is my 1st hackintosh i'm leaerning as fast as I can. thanks for your help !
