Whenever i boot up KSP with mods i will be flashbanged by a white screen with windows saying "KSP_64.exe is not responding", and i will have to wait for more than 10 minutes before it actually shows the loading screen and begins loading.
This issue only happens when there are mods installed, and varies based on how much mods.
If i install only [x] science continued and requirements the game will not flashbang me, instantly showing the loading screen.
How to reproduce:
1: install ksp (i use steam)
2: install a lot of mods (+100 in my case)
3: "KSP_64.exe is not responding"
Here is a list of all the mods installed when the problem occurs:
