Fixed bugs
Just fixed two (one, exactly, since they have the same cause) major bugs in my OpenCore EFI configuration files for Hackintoshing!

I never thought that it would relate to Bluetooth. I considered it as caused by the microphone (because it never worked on macOS) until I read this (Image 1) in the wiki of IntelBluetoothFirmware.

Then I followed this short but really useful guide, removed IntelBluetoothInjector.kext and added BlueToolFixup.kext (from acidanthera/BrcmPatchRAM). And everything got fixed dramatically! - Bluetooth, Mouse, Siri, and some other System Preferences panes don't crash anymore, even the OS startup speed, backs to about 10 seconds which is just on macOS Big Sur 11.

Anyways, huge thanks to OpenIntelWireless as they ported the Intel wireless drivers from Linux, and also OpenCore for providing us a blazing fast, casual customizable bootloader for Hackintosh. Again, this is the OpenCore EFI configs I'm currently using, you can have them for non-commercial using, modifying, and referencing: ThrRip/OpenCore-EFI-Laptop-Lenovo-Yoga-C740-14IML.
