--- Comment #1 from Esme Povirk madewokherd@gmail.com --- It appears to be obfuscated by something called ConfuserEx, which (oddly for an obfuscator) is open-source and indicates this with a module attribute.

--- Comment #2 from Esme Povirk madewokherd@gmail.com --- The image seems to have multiple "#Strings" heaps, with the first one having a reasonable size, and the second being empty. Mono uses the second one.

After fixing that, it still fails because the index is wrong.

--- Comment #3 from Esme Povirk madewokherd@gmail.com --- The failure happens in mono_image_load_names when reading the Assembly table. According to ILSpy, 4aaf is the blob heap offset of the public key, not the name, so not sure why Mono got that wrong.

--- Comment #4 from Esme Povirk madewokherd@gmail.com --- ILSpy has the explanation: Apparently there's an undocumented flag that adds an extra 4 bytes to the header of the metadata table stream (#~).

--- Comment #8 from Esme Povirk madewokherd@gmail.com --- As for the invalid method header format: what's most likely supposed to happen is that some method is supposed to decode that method in memory before the runtime reads it. Mono is probably doing something in the wrong order.

<Module>.cctor is called first and runs to completion. Afterwards, at least one method is called that dnSpy isn't able to display, indicating that it decoded successfully. That method never returns, though.

Some of what methods Mono is compiling and why may reveal something, but this kind of investigation is time-consuming, so I'm going to set it aside for now to triage other bugs in my queue.
