BIG SUR goes to sleep mode after Boot

[Bassem Adel]

i installed BIG SUR alongside Windows 10 several months ago and it was working without problems,
but there were some problems in Windows10 and I reinstalled it,

now when i boot from 'big sur' i get a black screen but if pc goes to sleep and wake up again i find pc work without problems >>
This means that every time I want to use MacOS, I must turn on PC > and then leave it until it enters into sleep mode > and then press any key until it wakes up > after that I can work on it !!

- i have disabled IGPU in BIOS
- I have completely formatted the hard drive,
- And I downloaded the New Big Sur Olarila again,
- And I Make New OpenCore 6.8 files again

and still same problem !!

This is my Power Management logs
