Issue:
Hy everyone! I have an issue when installing Big Sur (latest version and clean installation ) I used the recommended kex, and config.plist described in the guide for my CPU and hardware, I didn't receive any kernel panic and I was able to reach the installation screen but I have a strange issue when I'm in the installer screen, everything is working fine but after 5 minutes the system freezes randomly, at the beginning I was thinking that the issue was related to my mouse and keyboard but then I realized that all the system was frozen so I wasn't able to finish the installation of Big Sur, attached is my EFI file if you want to check it. The SSDTs where made using SSDTTime, from what I noticed the issue might not be related to OpenCore but to the kext or config file parameters that I used, i already try to modify and add some parameters that wasn't on the guide but were recommended in slowgeek sanity checker but the result it's the same, I have been dealing with this a couple days so I would appreciate very much your help!
