Your logs sadly did not output an error.

Can you maybe check if this provides a better error log?:

check Windows Event Viewer (Win+R > eventvwr > Windows Logs > Application > "Find" (on the right side panel of the window if you are using windows 10) -> KSA") for entries with source ".NET Runtime" or "Application Error" around the time you tried to launch.

If there is no error message there either i would try to do the following:

Ground Clutter setting seems to be the issue here.
Go to C:\Users\YOUR_USERNAME\Documents\My Games\Kitten Space Agency\settings.toml and change:
groundClutter = true
to
groundClutter = false

Solved for me. Issue happened even for Earth Only system.

I also noticed that your GPU driver version

Driver version: 22.20.27.09-230330a-390451C

is from Mrach 2023, so almost 3 years old and it might be worth updating the driver

We love a good driver update.
