Saved Vessels gone, Can't Launch

  • NVIDIA GeForce RTX 3080
• Description of the bug.  
  • Expected behavior:  All saved ships are present and the launch button takes me to the selected launch pad.
  • Observed Behavior:  I got my game in to a state where none of my saved ships were showing up.  I tried to go in in and out of game areas, restarted the game.. and nothing.  On top of that-- constructing a new ship, saving it and then trying to launch, the Launch button does nothing.  I hear the sound, but it just sits.  Restart the game,  load up the ship.. launch does nothing.  Pick a pre-set ship, launch does nothing.
    
    After pressing a bunch of navigation buttons  (going in and out of VAB, tracking, training)  it finally budged something.   My ships were showing up.. launch button works again.
    
    This is about all the information I'm aware of, not sure how it got in to this state.  I was stuck there for about a day.
• Steps to Replicate
  • Really not sure
• Fixes / Workarounds (if known..)
  • I was able to budge the saves in to existence by navigating around the menu quickly/aggressively.  I went in to the VAB and they were just there...

An update.  I launched one rocket, came back to the VAB and the vessels are gone again and launch button does not work.  I did not restart my game during that time.

I am going to start a fresh save.

Starting a fresh save without closing the game has fixed the issue.

You either have to close your game between each launch or, as you stated, create a new save.
