Strange crashing issue when attempting to use BepInEx with Crystar

[KingKrouch]

What happened?

When attempting to set up BepInEx 6 (x64-IL2CPP build) with the game Crystar (on Steam), it seemingly generates dummy assemblies and then crashes when the game is supposed to launch.

I noticed that there was an error regarding corrupt memory, so I decided to see if SteamStub might have been used with the game, but attempting to use a SteamStub unpacker on the game's main executable complains about the file missing an expected .bind section, so I'm unsure if there's some other form of obfuscation on the game executable, or if I'm simply just reading too far into it.

As far as I'm aware, this same issue happens on Windows 10/11 as well.
