No issues with the launcher, updated to latest version of Java, Windows updates, and latest Starmade build (v0.199.349). Game loads perfectly fine.
The game freezes immediately upon pressing 'R' to enter any ship core, regardless of how large a ship is (tested on lone core, and 10000+ mass ship, equal results).
Entering a station/build block works fine. Only ship cores cause the freeze.
(after clean installation) Start the game, start a new single player game, place a ship core, enter, freeze. I don't know what else to say.
