Your games crashing? You have a gpu thats easily capable of running this game? Then i am your man!
Check if youre swap file/page files disabled in windows (the backup ram that uses ssd space if your system runs low on ram)
I know it might sound crazy but i have a Rtx 4090 that was constantly crashing in many different games such as FF15 Res7 Deathloop etc.
Since ive enabled this setting again i had no more issues, no more crashes everything runs fine!
Thats a common windows bug afaik, when you disable the backup ram it causes various issues.

You can thank me with a prayer or a community prize ma little fellas

Search in Windows for: SystemPropertiesAdvanced

Click on Run as Administrator

Click on settings then go to Advanced tab

There youll see Virtual Memory, select it

Select change, now you can set the Ram. Its important to enable Virtual Ram no matter how much of real Ram you have.

Last step: Restart the PC
