Game crashes apon launching a craft

Just as I've said in your discord server; I launch a brand new rocket with sights set on Sergeaa in search of tech points. I successfully reach a parabolic orbit, then a stable orbit, low orbit, and finally a landing. walk around 116 meters, don't wanna burn my feet too much. Pause, save, and exit the game- not before saving the rocket in the designer. Next time I load up the game I use the same rocket(but with a different drood, of course) with aims of Vulco, nope! I watch the full loading screen as usual, but then the audio glitches a bit before the game crashes and kicks me out. Apon re-entering the game, I'm met with an error screen(built because if I can use device screenshots idk how) tdlling me a flight was detected and asking me wether or not I want to undo it. I do, then try to launch a few more times to no avail. So I try with different crafts from different launch locations and even from different worlds. Pointless. Nothing I tried works. Which brings me here.
