Regarding the issue of APEX not starting.

Ive been losing my mind over this same issue. Just CTD's all the time when playing at random times. Same exact error in my Event Viewer and it looks like the Driver for Easy Anti Cheat is the issue. Here's my output from running the "fsutil bypassIo state c:\" command: 

C:\Windows\System32>fsutil bypassIo state c:\
BypassIo on "c:\" is not currently supported
    Status:  506 (At least one minifilter does not support bypass IO)
    Driver:  EasyAntiCheat_EOSSys
    Reason:  The specified minifilter does not support bypass IO.
    Storage Type:   NVMe
    Storage Driver: Not BypassIo Compatible

Would also really love some solution to this.
