blank procedure entry point error

[yakev19]

The game (Tower of Fantasy, ToF) just recently had an update and this error started showing up. It used to work before that latest update.
It works outside of Sandboxie and only occurs when I try to open it via Sandboxie. I am using sandboxie to multiclient the game, so I trust the game.

tl;dr: Used to work, game (ToF) had an update and not work anymore. Game can run outside of Sandboxie.

Things I've tried:

1. The other colored boxes (Security, Application, etc.)
2. Allowed Network Shares
3. Reinstalling Sandboxie
4. Using older version of Sandboxie (1.15.8 specifically)
5. Reinstalling the game (ToF)
6. Delete box contents

The blackscreen was just the admin rights popup

Try again after deleting the contents of the sandbox.

I've tried that. I forgot to include it in the list since I muscle memory it after a update so the box doesn't have to keep updating the game.

I asked on the game discord and others are also experiencing the same thing, but also that it's happened before. They've mentioned that it can fix itself when the next patch drops in 8 weeks or something, but was hoping to get some earlier clues to fix.
