Undocking Locks up the Game help!

[Ace76inDC]

KSP: 1.12.5

Problem: Undocking Locks/Hangs Game

I've tried uninstalling Connected Living Spaces, FreeIVA, Konstruction, but problem still persists.  I have a multi-year mission wrapping up (easy to create errors I suppose), and the final undocking locks up the game and I have to force close.

Side note:  thanks in advance to all the troubleshooters out there!  KSP remains a fantastic game, hoping we get KSP 2 back on track.  

Mods installed:

(Generally stayed close to the KSP 1 Community Lifeboat Project)

SOLVED kindof

Boy I must really have an obscure problem, even with a build I started from scratch after KSP 2 crashed and burned.

Found the answer in a 6-year old forum post, have no idea why it works:

>>

@CaptainPanda Have you already tried to remove the input locks manually when this happens? If not, please try it the next time:

Just open the debug menu (alt + F12 or ctrl + alt + F12) and navigate to the 'input locks' window. The window contains a big button to remove all active input locks. If this fixes your issue (at least temporary until it happens again), chances are good that it is a mod issue and you should post a log file, so we can take a closer look.
