KSP 2 hangs at black screen on startup

[JebMeantToDoThat]

Pretty much what it says on the tin. When I start KSP 2, it loads the launcher, but after launching the game, a window appears that is black and stays that way. No logos, no sounds, no nothing. I've attempted running it from Steam, from a steam-generated shortcut, and directly from the executable, with the same result each time. I've also  verified the integrity of the files. There are no mods or anything (obviously, I haven't managed to successfully run it once!) The only unusual thing about my machine is that I have an eGPU (desktop GPU in a thunderbolt3 breakout box). Still, I haven't had a problem with any other game, and I've played quite a few.

Thinkpad T480
