[Infusion]

Hello Guys!
Trying to Google my problem for some hours at the moment, which leaves me here

I am running into the Problem, which you can read at the title
also, I am attaching some files underneath which may help

My system:
Asrock x570 Steel Legend
Ryzen 5600x
GTX 970
32Gb of ram at 3600mhz

Before I have the Option to boot I get one of those infos
"Failed to calculate size of dict field containing <empty> as type data, context <PlatformInfo>! Which then disappears, before the actual boot process starts
Also My graphics card seems to make some error's because the picture seem to go off and on
also tried different smbios versions, like google suggested

i used the dortania on github.
at this point i am completely lost what I could do possibly do wrong

Your PlatformInfo section was a mess. Part of it was in NVRAM and you hadn't changed the core count patch. This should work now.

Also keep in mind that GTX 970 is supported up to High Sierra and you need to install the nvidia web drivers.
