So I realize this is a bit of a necro here but this is one of the only threads I've found to the issue that I have been currently experiencing.
I have been having the exact same issue as Brettapuss. It started 2 weeks ago but I didn't start diagnosing or trying to resolve until really this weekend.
Right off the bat though I can confirm that this solution posted above does nothing to resolve the issue.
I won't bother going into details on how I was diagnosing the issue because that was super involved and very scattered.
But ultimately I have come to the conclusion that its really nothing to do with Ark or BattleEye but actually windows, or in my case Nvidia, that is likely causing the issue.
And after doing everything...and I mean everything to resolve it.
And ultimately failing. I am going to have to wipe the entire PC to fix it. Not great news.
Ill post later after the formatting is all said and done to let you know if that fixed it...because if it doesn't than really the only other thing I can think of is a direct hardware issue.
