Heavily modded game freezes on "Expansion Loading Complete" every time since last update

[qwery123]

Since 1.12.4 came out, the game has frozen at "Expansion Loading Complete" every time I try to play it, and then crashes after around 45 minutes. I tried to revert to 1.12.3 using Steam's beta function, and it did not work. Maybe this has something to do with the new launcher, which does not disappear when I use the previous version as a "beta version"? Unfortunately, it is hard to debug it, as KSP does not record anything to KSP.log while frozen, and it did not put a crash report inn the log.

This is why you don't install mods in the Steam copy of KSP- Steam breaks stuff all the time, doubly so when the game updates.

Fortunately, it's easy to create copies of KSP and put your mods in those, safely out of Steam's reach:

1.       Right click KSP in Steam library > browse local files.

2.       Copy KSP/saves/<your save name> and paste that on the desktop.

3.       If you used CKAN to install your mods (and you should!), click File > export modpack and save that to your desktop too. Screenshot your GameData folder with mods installed (even if you use CKAN) so you can check that you’ve reinstalled them all later.

4.       Uninstall all mods from KSP.

5.       Right click KSP in Steam library > properties, disable Steam cloud.

6.       Completely uninstall KSP through Steam.

7.       Reinstall KSP through Steam, right click > Properties > local files > verify integrity of game files. If you want to play a version other than the current release (1.12.4), pick that version in the Betas tab and verify the files once Steam has installed that version.

8.       Run KSP and make sure it loads properly without mods.

9.       Browse local files again, then go up one level (to Steam/steamapps/common) and copy the Kerbal Space Program directory, then paste it where you want to keep it- make sure it’s outside Steam’s folders so it can’t meddle with it in future.

10.   Rename the KSP folder so you know what mods you’re using in it (e.g. 1.10.1 RO/RP-1, 1.12.3 JNSQ), then add this new copy to CKAN and use the modpack created in step 3 to reinstall all your mods; or reinstall them by hand if you don’t use CKAN. Double-check that all files and folders you had in GameData before uninstalling/reinstalling everything are there again, if not then you’re probably missing some mods.

11.   Move your saves from your desktop into your new KSP copy’s saves folder, run KSP, load save. A warning about vessels having missing parts is usually because a mod is missing or wasn’t installed correctly.

You can make as many copies of KSP as you want, have several copies on different versions and with different sets of mods in each- CKAN makes this much easier to keep track of, but it’s still possible to do it all yourself.

You can also run KSP without the launcher by just deleting the launcher from the KSP folder and running the game using KSP.exe, either from inside the folder, by creating a shortcut to it or using CKAN's "launch game" button.
