Is easy anti cheat installed?
Can you re-install it? (i.e., is this possible?)
Can you temporarily remove it and reinstall it later?
If you respond no to each question, try a clean startup (or clean boot):
- Start, searchbox, type msconfig, press enter.
- In the new msconfig window, in General tab (default opened tab), click Selective startup and untick/deselect Load startup items.
Only that one should be unticked, the other two must be ticked. - Go to Msconfig Services tab, tick/select Hide all Microsoft services.
Don't forget to hide them!
Disable the remaining NON-windows services.
I.e., DON'T disable windows services! - Click ok, reboot
- Verify if the problem persists.
