Hi,

Try to disable all useless parameters that I found in your rpt

-maxmem=2047 -maxvram=1025

You´ve got loaded your Arma3.exe twice

== "D:\Steam\steamapps\common\Arma 3\arma3.exe" "D:\Steam\steamapps\common\Arma 3\arma3.exe"

so try to relocate your Arma 3 folder to some SSD or try it to re-install. Also, you can try to check your firewall which can cause the force quit from servers.
