I have the same problem, might have a look Gredwitch

I have the same problem

fixed . idk how

Same problem

same problem

yeah ... same

just try everything you can think of... restart the PC... disable some addons maybe?

thats might be it and gredwitch said that you only can activate the camera when you press ALT but ALT is not working so you cant really turne it on only when you press ALT

and you need to be in 1first person mode idk what gredwitch means

LFS doesn't automatically bind things like camera to keys, you'll have to go mess with the LFS binds yourself to fix it, be careful how ever since editing LFS binds will change all binds so you may end up with a few problems if you don't bind stuff correctly.

How to readjust LFS？

C -> LFS -> Controls (allow it) -> Bind Freelook (Hold) to Alt button
Then u can sit in Helicopter and turn on the camera by clicking Alt+V

what is the default bind for camera

Reset your gmod if that doesn't work then I have no idea.
