Return of Reckoning

I get this error at launch, game launches and works normally but it seems i have huge lag spikes and more crashes then my friends

Data.myp:
System.InvalidOperationException: Impossibile caricare i dati del nome del contatore poiché è stato letto un indice non valido '' dal Registro di sistema.
in System.Diagnostics.PerformanceCounterLib.GetStringTable(Boolean isHelp)
in System.Diagnostics.PerformanceCounterLib.get_NameTable()

I've already removed read-only restriction from all the files, granted administrator rights to the launcher and executed the commands on the cmd as mentioned in other threads. I've also tried redonloading clean client, reinstalling and changing the data.myp with one from a friend who doesn't get any error.
Any idea on how to fix?

Have you tried as well?

Yes i did both the command lines suggested in the other threads.

In case it could be useful i use windows 10 on a Amd A10 machine
