OpenCore ACPI Exception Big Sur: AE_NOT_FOUND During name lookup/catalog

I am running Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina at the moment and it works perfectly on my system using OpenCore. While trying to install Big Sur, I get stuck during before setup. I have setup EFI folder from scratch using latest OpenCore. I tried both prebuilt SSDT as well as custom SSDT using SSDTTime but without Success .

I have attached EFI Folder and error screenshot

Errors:

No local variables are initialized for method [PXSX]
