So I've been playing the Blood Launcher with no problems up to E4M6, but now there's this mandatory fireball trap that crashes the game every single time. It's in this room with two skull switches that lower a pillar containing a key. As soon as I pick up the key, the columns reveal fireball traps, and shortly after they start shooting the game crashes. I've tried every single graphic mode and the crash happens at exactly the same time. I've also tried leaving the room as quickly as I can when I pick up the key and it still crashes.

Help?

Have you tried any of the compatibility settings from right clicking the shortcut and going to properties?

Also if you can't figure it out and want to get passed that part fast just press T to talk and type in keys. The cheat will give you all the keys for the level but then you won't have to trigger the trap and you can still collect the other keys if there are any like normal.

Yeah, I went through the usual compatibility stuff and it still crashes. I skipped that part by noclipping through the key door, but it's still puzzling why I haven't found anyone else who's had this problem.

Yea its a bit odd. You'll have to see if anything else later in the game causes a consistant crash.

Just played through the whole game (including the expansions) and nothing else crashed consistently. I did have one random crash in the steamboat level but was unable to reproduce it.

I wonder if a file got corrupt in the install then unless its a known bug and happens to others? Probably worth a full reinstall if you decide to play it again in the future just incase it solves the problem.

I played through the game again, this time on the hardest difficulty. Got to the part that crashed before, and this time it doesn't crash at all. I kept a save in my previous game, so I loaded that and sure enough, it always crashed at that spot. So apparently that particular game got messed up somehow.
