Does windows start?
if so
1) open CMD as admin
2) diskpart
3) list disk
4) be sure which one is OSX disk (ie disk 2)
5 sel disk 2
6) sel part 1
7)assign letter=b
in this way you assign a letter to your EFI partition and this will mount your OSX EFI partition
to see inside you have to use or total commander or OCAT or browse it with Task manager browse (i use this method)
you can copy or modify things to recover any problems
ps
If you are confident reading this instructions you can proceed , otherwise do nothing

no apfel-baum no good idea because often those update solve some problems
I have written also here because former download-fritz follow this forum and maybe it could be solved in Opencore bootloader before adding other patches for AMD system
Opencore devs does not support directly AMD CPU but if some coder/dev propose solution they listen and help (if it is not against their bootloader roadmap)

Hi
New bios upgrade for Asus x670E hero motherboard breaks compatibility with OSX.
This bios has a initial support for incoming new AMD CPU and new agesa.
Others OS like Windows or UBUNTU aren’t affected by this big problem.
Attached opencore ‘s sys report for both working and not working bioses (1602 vs 1709)
Any ideas?
Edit:
Obviously it is possible to downgrade easily to a working bios

i will try to explain better
i use to have two OSX disk
one with Ventura and one with Sonoma
Ventura does no need to patch frameworks or kext to use Wifi/bt with my broadcom
Sonoma needs of many patches that OCLP does for us
so in config.plist you can say to opencore bootloader to apply the kext or the patches only to Sonoma
for this opencore use min/max kernel parameters
se my config in this pictures:
23.0.0 means to apply this kexts from Sonoma OSX and above
this means that opencore block this kext only for OSX from Sonoma and above
it is also possible to use multiple EFI using a tool (not supported i think from OC developer) bootloader chooser to have different EFI for different OS, but this is another story:)
Sorry for english but i am not able to write in german language

muse_83 you can prepare your config.plis (kext, block, amfi , SecurebootModel and SIP)
but frameworks must be patched in Sonoma OS
so you can adjust your EFI, then update to Sonoma OS, and only then you can run OCLP Sonoma version to patch Sonoma frameworks
if you use different OSX remember to apply min and max kernel to avoid problem in previous OS
