Bully is a poorly optimized game. Stuff like that can happen out of nothing with that much stuff on screen.
I played the game countless times with reshade, no issue. (yet again is easy to just unload all effects)
Maybe if you return the render distance (draw distance) back to normal will get solved?
If you still have issues, try that and also getting vanilla textures back.
When modding goes wrong, it's a good practice to return no vanilla and try again step by step (mod by mod).
By the way, if you still have issues after that there is a good chance you messed up your save file
(it's very unlikely, but wouldn't surprise me that much)....
