Just quick update, win11 already has those settings in there, due to i wanted to go change it, but what did work for me was Bios update lol, u see GW updated the 11th and 12th cpu settings in the game, if u run a 13th or 14th gen CPU, u will have to update to the latest bios updated, LONG story short, found Youtube vi about intel cpu's that has drama, aka 13th 14th, once u update to the NEW BIOS build BOOM sorted, game loaded, reliving the Imperial space fleet STEAM ROLLING those XENOS SCUM!
Also advance launch has nothing in it. BUT u can still tinker with that SHOULD u maybe get some problems, some cases that i read ppl disabled Internet before launch.

unfortunately, none of these options have worked for me

Thanks for the tip, I confirm that it worked for me in July 2025 on a new laptop with Intel Core Ultra 9 275, Windows 11 and RTX5080.

More precisely, my windows environment was already containing all what is indicated. What actually fixed the issue for me was to add the following prompt in the Steam Launch Options of the game:

"setx OPENSSL_ia32cap ~0x20000000"

The real key here is the "x" collated to ''set''. Typing only "SET" as suggested in some comments of this thread does not work and generate an error message in Steam when launching the game. But the above prompt (without the brackets of course) did work and finally allowed me to enjoy the game without any crash.

All good, I reversed the changes if I'm not playing by deleting the System Variable. I was using the second steam launch option, didn't realize it was a CMD command woops

@Ace Hazume YT
What do you mean by that?

Will this affect future games?

Thanks, fixed it.

i dont know why the alt launch option worked for me when i tried creating a var and that didnt

my specs are 14th gen i9 14900k
and an rtx 4080 super

Som additional info: the change made with cmd /c "set OPENSSL_ia32cap=:~0x20000000 && %command%" will not persist after a restart. Here's why: Command Prompt Scope: This command is executed within the current command prompt session. Environment variable modifications made this way only affect that specific session. System-wide Variables: To make changes to environment variables that persist across restarts, you'd need to modify them in your system's environment settings.

I don't have any other games made in Unreal Engine 4 that had this issue, so I was looking for a fix that I could apply just to this game alone without adding environmental vars or messing with my computer too much. Thx for the alt launch option!
