Crash With Somewhat Extensive Modding (cause unknown)

[Rambow_Ninja94]

Hi,
It's not often that i come to this forum to ask questions on bugs, because i usually find probably suboptimal, but working ways to fix them myself. But this time i am completely stumped...
About 1 month ago i booted my main KSP save (which is semi-extensively modded) and it spent the usual 40 minutes booting, but then on the loading page (after giving me the usual error messages that are just textures missing from redundant parts) it just freezes before loading the menu, stops trying to utilise disk, maxes out memory, converts itself into a backround task and sits around for 20 minutes not responding before the unity crash handler kicks in and it closes itself.
Prior to this i had loaded the game thousands of times with the same mods (or older versions) and never had this issue. 
I had updated to 1.12.3 2 weeks prior but i checked all the dependency's and had run it fine on that version several times.
I had done nothing to the mods file since the update to 1.12.3, and i am unable to find out the cause of the fix.

Overall I have probably spent about 11 hours trying to fix this so if the issue is really simple I'm gonna be embarrassed, and i am no closer to figuring it out. If you can fix this (or atleast tell me what else you could need to fix it) please help, i don't want my kerbals to be stuck in simulated deep space forever.

Attached is a screenshot of the menu failing to load and about 20 seconds before the whole thing crashed, and my modslist (although bear in mind it has run fine with these before) and the logs.

That is pretty odd. The Player.log just stops abruptly,  without a stack dump or even a error message.

So all we can do is to guess.

Find and remove all directories (and contents) called @thumbs.  There's a known bug on KSP that makes it to crash when a thumb image file is damage.

If by doing this the problem persists, consider verifying the game's integrity if you are using Steam, or re-download it if using other shop.

But, again, I'm wild guessing - I have no clue about what's happening on your rig...

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 (1.12.5), 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 version it is and what mods you’re using in it (e.g. 1.12.5 JNSQ, 1.7.3 Grand Tour etc.), 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.
