I've tried both the older version of the game and the new version, both I allocate 16 gigs of my 32 gigs, and on about 4 different launchers. All have the same problem, after about 5 minutes of playing, the game freezes my system then crashes to desktop,

if I'm posting incorrectly please excuse me, this is my first time (besides the tombstone lol) that I have posted and am still learning.

thank you for any help

That's just a warning and not the thing that crashed the game, I'm sure your game just runs out of memory and crashes with a weird exit code, try allocating only 10GB
