Hi, I had the same problem twice, my game was stuked in the loading and then crashes. I fixed in another way and would like to share for the people who had the same problem.
What I did to fix:
- go to folder saves in the KSP file (C:/Program Files (x86)/Steam/steamapps/common/Kerbal Space Program/saves/*Last Save Name*)
- delete the 2 files called persistent one with extension .sfs and anothe .loadmeta in this folder
- you are ready to go.
If didn't work, then to this:
- Steam workshop and unsubcribed all things (ships and mods) off ksp.
- Unistall the game.
- After unistalling the game I did DELETE all the Kerbal Space Program in the local files on Steam directory.
- Intall the game and run.
Let me know if I could help who had the same problem and didn't want to delete Steam...
PS: Sorry for my English. I'm learning
