Constant crashes, later on in "Surface Tension"

Black Mesa Archive In-game Issues (Mod)
#1

I’ve been having problems in “Surface Tension” - in the tunnel after the battle in the foyer, once you’ve managed to get outside, Black Mesa keeps experiencing CTDs when I try to open the door with the keypad. I’ve tried everything I can think of - turning in the opposite direction to the loading area (which worked for me before), dropping the settings down as much as possible, restarting from earlier saves… but nothing’s worked.

The .mdmp file from the latest of MANY crashes in this area is attached below.

EDIT: And, of course, as soon as I posted this, I tried again… and it WORKED. GAH!

EDIT 2: And, a few minutes later, it crashed, and all “Surface Tension” saves I had won’t load. Why the hell…?
