Anti Cheat may reject any stray files. This is not a bug or anything we can (or want to) do anything about.
The reason it works on Linux is that the Anti Cheat doesn't work exactly the same as on Windows and works together with Proton which dxvk is a part of.
In other words, EAC is just working entirely as intended.
Nothing extracted yet.

System information
If more information is needed please let me know, this is the first time using DXVK, was told it may help with me micro stutters potentially caused by EAC, a friend on linux said it should work since its what he uses when playing Rocket League as its just a translation layer.
