There's been a similar issue 6 years ago: https://github.com/doitsujin/dxvk/issues/102
Has anything changed since then?
Using the Steam version the game starts fine here with both Linux Proton and Windows using a RTX 4080. Don't think it should matter if it is the Epic version maybe besides trying to turn off the overlay if it has one.
Try to update your driver and check out the Windows section in the readme https://github.com/doitsujin/dxvk/wiki/Windows
Most likely just another Windows issue:

Will try updating the Driver, and will post here if anything changed.
Found the issue, It was because both of the Driver being outdated and RTSS hooking onto the game.
Updating the Driver, and Closing RTSS fixed the issue. Hope this helps anyone else with the same problem

Apitrace file(s)
Log files
DXVK Config maybe something conflicts with the game, but I have tried without changing anything in the 'dxvk.conf'
dxvk.txt I changed it to TXT format so I could upload it.

Also I'm playing from the Epic Games Launcher... Unsure if it might work on Steam.
After Starting up the game, the game completely crashes with the UnityCrash handler starting up, and after a second or less it closes too.
