Is there a way to fix this?

Have you applied the 4 GIG patch?

Solved my issue with it.

Seems to have worked for me. Thanks.

Wow so far so good after applying this.
Why would this not be somehow automatically implemeted. I mean I was a moment away from leaving a bad review and never playing it again because the game just kept crashing.
Now hopefully I can make it through the game in its entirety.

I played without this (I was able to do it with a lot of save after crash + affinity cpu to only 2.. 1 was lagging without crashing more than 2 crash a lot more)... But I'm glad you were able to find a solution to totally avoid this problem.
Next time I will play with this.

Yeah 4GB patch is the way to go. I've had several lengthy playthroughs without crashing issues. I wouldn't mess with the core affinity unless you know for sure your system requires it.
