Attempted solution given in linked thread. Only been using the "Not forcing any compatibility tool" option for this, as that seems to be the only one giving results. No amount or combination of opening launcher, disabling Steam overlay in Steam settings, and then running the game changed the issue. Running in offline mode does not cause the screen to freeze for five seconds before the game crashing, but rather causes the game to crash after about one second and give the following error message: EDIT: the forum won't let me post with the error message in the reply. Apparently I'm trying to spam the forum. Short answer is it's an error/exit code 139.
I have verified the integrity of the game files since then, to no effect. Running in offline mode still produces the above error. I have no mods, and while strictly speaking I have the "The Victoria II Remastered Soundtrack" DLC I've made sure to disable that just in case. "More details" option gives the following:

On a separate note that might help Paradox/others, might this be an interaction between Victoria 3 and the Steam Overlay, rather than just being an issue with the Steam Overlay? Stellaris, for instance, has no problems with this - at least, not on my machine. Nor does any non-Paradox game that I own, this is an issue exclusive to Victoria 3.
