I just want to get to the start screen, how do I remove the intro warnings and stuff?

Yepp, also searching for that clue

With all the CTDs, would be pretty handy yeah. They're probably buried in one of the big game archive files. Sometimes, those can be opened with archiving software, and I'd wager if you look up how to open Wither3 game pack archive files, a similar way might apply here. I don't have W3 tho, so I can't compare.

You can find the "No Intro Videos" a mod here, I tried it and it works.
