IPA with TrollStore Black Screen upon Launch

[FireMario211]

Vague problem but for some TrollStore users, launching Geode will result in a black screen and an "Error enabling JIT: trollstorehelper returned 3" error.

Installing dopamine or using TIPA version with dopamine seems to work, but TrollStore should work regardless.

as after receiving a log from a user, it never goes to the guest hooking part.
