Helo!
I have the same problem. And today looking for a solution in a group on Facebook, I saw that more people with the same problem.
We tried to help each other, but we couldn't solve it.

We tried to reinstall the game. Update everything. To set up. Clean. Everything.
The problem started while I was flying for a mission. Since then, after selecting the character, the game closes.
I tried to create a new character and the game opened. I can't understand what's going on.
I would love a solution from Square Enix.
