There's actually a check for staging I think, a 0.5 second delay. No idea if the check can fail/get locked so you can't stage. But you can try to remove it by setting it to 0.0 in %appdata%\LocalLow\Intercept Games\Kerbal Space Program 2\Global\PhysicsSettings.json riiight at the bottom. Use Notepad++ to edit it ideally, save and reload the game
