Last Dose 5 Crash

I’ve played all the first dose and last dose missions except the final one due to the game crashing every single time I get control of the cargo plane, I don’t know what to do to fix this. I’ve tried lowest graphics settings possible, verified game files, currently redownloading the game to see if it fixes itself.

I don’t know what to do, I’m just trying to finish the mission so I can get the storyline done.

The game runs perfectly everywhere else, so I’m very confused.
