Il2cppdumper stopped working on Standoff 2

[zolotov0]

• Il2CppDumper version 6.7.40

• Unity version 2022.3.19f1

I always get an error. Apparently the developers broke the metadata (did not encrypt it), the dumper doesn't even get to the point of initializing il2cpp.
il2cpp & metadata.zip

Initializing metadata...

[rjukankukan]

a lil hint for you - load metadata structure in ida, apply it to s_GlobalMetadataHeader and compare outputs in 0.27.3 and 0.28.2

i don't think that the fix can be automatized, but who knows

[Fadeyauso]

did you fix it?

[rjukankukan]

it's fixable, but this is literally a cat-mouse game - i'll publish the fix and they will find another way to break the metadata
i posted a hint in my prev comment, those who search always find the solution
