Aircraft becomes unresponsive

[Shrimpz432]

I just purchased this aircraft today from the marketplace and apart from some minor issues that were fixed by restarting my pc it works great but sometimes the whole sim freezes but the aircraft is still moving and I can't move my camera and pressing buttons in the aircraft does nothing I can't even exit the sim properly so I have to alt F4. So is this some type of WASM crash or something else? Also when I go into third person view then get back into cockpit view my FPS drops but it fixes after a few seconds not a big issue but still annoying.
