H4 campaign crashing with 4 player co-op about alpharing

[LvnarNeko]

Not entirely relevant to the main issue, but both H1A and H2A with updated graphics would load in the other players and make the split screen dividers, but the game itself would not split the screen accordingly. We could still move and shoot with the other players, but they would have no screen unless we flipped back to original graphics which instantly restored everyone's cameras.
Is this an issue with the way the anniversary editions were made or an issue with the mod? Thanks!

Are you using modded map?
Cause there is a known issue when you play modded map and there is a chance that the game will access invalid memory using function BinkGoto.

We are playing with no other mods, just yours.

Which version did you use? Have you tried the dev build?
This is the first time I heard someone would crash the game while adding player 4 in h4.
If the dev build doesn't work, then you have to debug the game by yourself and then tell me where the exception point is (in [module + offset] format), as I can't reproduce this issue.
Btw, the anniversary splitscreen graphics issue have been answered here.
