can't press the launch and revert to KSC buttons in the VAB because of a NullReferenceException

[Starhelperdude]

I have the problem since a long time, I'm playing on a modded 1.11.1 install and everytime I go into the VAB and launch it works, or if I go into the tracking station it works, but if I want to launch a second time or go out of the tracking station and go into another building it doesn't work and I'm getting a NullReferenceException. I only have this problem in this modpack, I have never encountered it anywhere else.

question: is the error message here sufficient for the locationing of the problem?

Spoiler

do the buttons acknowledge that you have a mouse over them?
If not, you may want to use the altF12 menu to clear input locks.
If they are interacting, then this is out of my field of expertise

yeah, they interact, I also cleared the input locks multiple times but it didn't work

Sorry then, Id just advise removing mods 1 by 1 until the issue stops and then putting all the other mods back in and repeating the process until the issue is fixed.
Sometimes a PC restart helps as well.
Other then  that, cant help (soz)
