black screen during installation on Lenovo Yoga C940-14iil

[lqgmeow]

Hi, I'm trying to install Catalina(10.15.7) on my laptop Yoga C940, after boot from USB installer with no problem, it reboots to my SSD, then I see some kernel panic stops my installation. I solve that by mmio whitelist, then I noticed that OpenCore picker is not shown on my screen anymore (it does be there in the log file). After fixing another panic, now my problem is:
When I boot from my USB, I can see the OC load massage, then I see a black screen rather than the picker and [EB:...] massage. Then I suddenly see the output again, after some ACPI error, finally it stops and the screen get darker, after a while just a black screen.

I'm a new guy in hackintosh, and I don't even know how to describe this exactly, so I'm sorry for just saying "black screen" in the title.

This is my hardware, mine is i7-1065g7, 16GB and 4K display version, and I have replaced the SAMSUNG SSD to WD SN550: https://psref.lenovo.com/syspool/Sys/PDF/Yoga/Yoga_C940_14IIL/Yoga_C940_14IIL_Spec.PDF

I use OpenCore-0.7.8-Debug, and create my USB installer from App Store on my desktop hackintosh. Here is my EFI with the latest log file. Thanks very much if anyone can help me!
