Dedicated server starting issue

Evening! Recently I'd decided to create my own server to play with my friends, so I found guide for creating it. However, following the instruction I faced few problems in cmd after launching start.bat file. I'll attach some pics so you will understand situation better.
I made this server using steamcmd
I used these commands to create server:
- login anonymous
- app_update 403240 validate
In created directory I made new start.bat file

After launching start.bat shows up those errors(attached in beginning(cmd)) , cmd continue working without crashes and server isn't in the list of custom browser.
All of my ports are open
I have a assumption that it can be connected with recently came out big update 4.2, but there is a new question comes out, how other servers work?
ps: version of my game is
