Severe case of desync

Hi, network is stable, no packet loss, ms betweeen 30-40ms, ttl 112, (in huge tests through pinging google), I was able to play the entire campaign yesterday, today I can see getting hit, I am able to kill mobs that are invisible (their corpses show after sometime), also when playing with friends, in the monolith room, when I enter the portal to start the monolith, in my screen I stay in that room, but they see me moving and casting without delay, I wasnt able to fix it, if you need more information I will try my utmost to deliver it, peace out

Edit: this guy found my fix! Arcane Ascendance skill with Acuity Specialization causing desync

I have the same issue, I made topic for that earlier today

Edit: I connected my phone to the same wifi and connected pc to phone via hotspot. For now desync is gone.

Any idea what can be the cause and how to fix it?
