Stock on "AmiShimTimerBoostExit changed current period to 549254"

[Pahanius]

Hello everyone,

Trying to launch Big Sur installer from USB drive. I'm completely adhered to OpenCore Install Guide from dortania.github.io, but installer not started.

OpenCore 0.7.4 logs stocked on "AmiShimTimerBoostExit changed current period to 549254", after that starts another log and blicks screen with crossed around and freezes on "AppleUSBHostPort::disconnect: persistent enumeration failures" (screenshot attached)

My PC:
Motherboard: GA-H170N-WIFI
Graphics: Built-in Intel 530
WI-FI: m.2 Broadcom BCM94352Z
CPU: Skylake i5 6600

Now Catalina with Clover 5122 is working perfectly on this PC.

Also I attached BIOS settings as photos

Could you help?
