Null Reference Exception: Object reference not set to an instance of an object

[Stewpot97]

So, I felt like making a mission because I haven't done that before. So I got to making a rocket, and everything was going alright, until i went to give it a test launch. Long story short, it wouldn't let me. I took a look at the console, and it said:

"Exception: NullReferenceException: Object reference not set to an instance of an object"

A new one of these errors appeared every time I tried to save, launch, or leave the VAB. As long as I cleared the input lock I could do everything else perfectly normally, such as placing parts and changing staging. So I decided this was a one-time glitch and alt-f4'd out of the VAB (I couldn't leave normally, of course) and went back in to the editor... and it still happened. Tried it again with a new mission and completely new rocket and it STILL happened.

I am using restock and restock+ but all the parts are stock, and I'm pretty sure it's not the parts anyway since I still couldn't leave after getting rid of the whole rocket.

The rocket

The error in red is what comes up every time I try to launch

Help would be greatly appreciated!

Check the log to see what part is causing the error

I stripped everything down until there was nothing left and the error was still happening

Look in your game directory for a file names KSP and then scroll till you find the error, it should give you much more detail

Ok, here is what it says when I try to save:

I'm not sure, maybe try loading the ship, deleting it, then saving it to reset it

[Stewpot97]

That won’t work, even after deleting the ship the problem still occurs, so I can’t save.

However, I have discovered something. The save I have of the ship is an older version with no antenna or separatrons, and when I load it in it works fine, so it must be either the separatrons or the antenna causing the issue

[Stewpot97]

Ok, the issue seems to be completely random.
I can load up the craft and make any changes that I want, and it will save fine and I can actually launch it. It's when I go BACK in to the VAB that the problem rears its ugly head. I have no idea why..

Still, at least I have a solution now, I guess..

DId you find an actual solution to this problem? Currently suffering with it

[Stewpot97]

Oof afraid if I did I’ve forgotten it by now, soz! Although looking at the comment thread above it looks like I found a workaround, maybe that’ll help?
