Hello @linuxgurugamer!
Happy to see you are such a good "parent" to so many wonderful mods from years past that older players like me miss and like to use!
Recently returned to KSP and installed a few mods. I did use CTB back in 1.10, I believe and remember I never encountered any issues. On 1.11.1 though, CTB causes some of the buttons to become non-responsive - in VAB, in the SPH, etc. Cannot click Launch and Save, Load a vessel works only sometimes after angry clicking. The Parts, Action groups, Inventory, Crew buttons work though. The issue seems to "spread" from the SPH and VAB and if I manage to exit them back to the KSC scene, Loading or Saving popup menu buttons also become non-responsive.
Clicking any of the aforementioned non-responsive UI elements results in an immediate nullref, as seen in the screenshot below.
Here's a list of mods, as output by CKAN(after my issues started I switched from my preferred manual method of mod installs to CKAN, just to confirm I am not installing an old version of some mod or a dependency by chance).:
