When I press "PLAY" in the client, the status goes to "Launching" for 1/2 second, then "Running" for 2-3 seconds, and ... nothing. Button goes back to "PLAY" again. I can't even catch anything in Task Manager. I'd post a log file, but I can't find any. No "Ksp2.log" is generated. The only interesting new-ish file I can find is ".crash", and it's empty.
But when I launch the game by running "KSP2_x64.exe" directly, everything starts up and runs beautifully, "Ksp2.log" and all. Not that I really care, I ran KSP1 outside the client anyway, made it easier to juggle mods and versions. I'm mostly missing "playtime" and possible achievements.
KSP1 starts without problems through the Steam Client, of course.
Win 10, latest Steam Client as of 3. Jan 2024 (reinstalled from scratch), KSP2 0.2.0.0.30291 (reinstalled from scratch).
