I'm running Ubuntu, which is basically Debian, so I tried my luck and yes, those packages existed with those names and versions. Installing them as instructed, rebooting the computer (probably restarting Wayland would have been enough, but whatever, this took less brainpower) and launching the game again almost solved the problem for first. It did crash in the same spot again, but then I went to the launch options, removed the line I had there before and replaced it with the debug line. After that, the game launched properly and I was also able to load my save and be back to Megaton where I happened to be the last time I saved (after getting scared of some super mutants).
My apologies for not obeying you completely, as I have already mostly played through Fallout:NV, and Fallout 3 is more interesting to me right now 🤪
So, the game's working now. Thank you! :) Apparently my Ubuntu had somehow removed some of the drivers in the background. On whose permission did it do that, if I may ask? Grr.
Once again, thanks! <3
A natural death at an old age?
Nah, nazis deserve much worse than these asses.
