I read that to make this future proof for big sur they have made some changes see this from 2.0.8 change log

  • Added constants for 11.0 support
  • Property 'pci-aspm-default' with value 0 is not required for Broadcom BCM4350 chipset (with non-apple subsystem-vendor-id), since now it is injected/corrected and method IOPCIFamily::setASPMState called for provider to disable ASPM immediately.
  • Add required dependencies into OSBundleLibraries section
  • Remove injectors for AirPortBrcm4360 and AirPortBrcmNIC from main Info.plist and move them into separate plugins AirPortBrcm4360_Injector and AirPortBrcmNIC_Injector (kexts with plist only). Under 11.0 (Big Sur) plugin AirPortBrcm4360_Injector.kext must be blocked by MaxKernel 19.9.9 or just removed, otherwise it will block loading of AirPortBrcmNIC since class AirPortBrcm4360 is unsupported.
  • Check whether brcmfx-driver value is incorrect (if specified value is unsupported in current osx system)
  • Support boot-arg and property brcmfx-aspm to override value used for pci-aspm-default

I am not able to understand this but is it due this changes it broke something?
