Make sure the ACPI tables are present in the ACPITables folder, and that you're using the correct path to the ACPITables folder. Dumping the ACPITables again is also a temporary solution until I can check the error accurately

I did check that the necessary .aml files are present and also checked that I'm using the correct path. Tried dumping the tables again too, but made no difference.

Forgot to mention that it fails to load the ACPI tables in the Hardware Report step, but lets me continue the setup until I get the same error I mentioned above.

Please drag and drop ACPI Tables folder here: C:\Users\vendor_dlkm\Desktop\OPCS\HS\Results\ACPITables

 - apic.aml

There's no error in loading the ACPI tables or creating the EFI anymore. Issue's solved. 👍
