Main.Exe missing
 

So i was playing whola day today, and just now my Game closed. Tried to launch it again and it says Main.Exe is missing. What do i do about that? And it keeps doing that even if i re-download the client and re-install the game aswell.
Im on Windows 10. I have Disabled the Real Time Protection on Windows Defender and my Anti-virus has been set to silent.

Delete all antivirus or windows firewall shut down or play game !

add game folder to exclusions and run launcher 2 to re-download main.exes
