Game Leads to PC Crash after about 15 Minutes

Hello, 

I have an issue where the game basically crashes the whole system after about 15 minutes playtime. Those crashes after 15 minutes are quite reproducible as I used my phones stopwatch to confirm the game's runtime. 

I already Up/Downgraded my Graphic driver, fiddled with the windows security settings and upgraded the bios of my mainboard. Nothing really helped. The windows installation is also quite fresh (I bascially re installed it before installing and launching the game). Reinstalling of the Anticheat software and verifying the files in steam also did not help unfortionatly.

It seems like there was a big patch yesterday when I wanted to play for the first time (steam downloaded about 30 GB). So I'm wondering, if they intruduced an issue here. 

Hardware Specs:  

• AMD Ryzen 7 7700x
• Nvidia RTX 5070
• Asus ROG Strix B650-e f Mainboard

For whatever reason, my friend which is using an older Ryzen 9 5xxx Chip and a RTX 3070ti gpu does not have any issues so far. As more people having issues with the newer AMD Zen3 chips, maybe the issue lies here? 

Is there any solution or fix planned for this issue? If not the game is unfortionatly not playable for me and therefore I would file a refund on steam.
