Perhaps, like me, the game crashed from pressing the aiming button. Sometimes on missions, sometimes just like that.
All you need to do. This is to go into the settings – and set the aiming button to F12 (or any other), and the right mouse button as an additional.
As a result, the game didn’t crash for a long time. Now I’m not afraid to pull weapons out of my pockets.
However, I was unable to test this method on a jewelry heist. Well, you don’t really need a weapon there. (I passed without it)
