Sending client info crash only on my server

Hello,
95% of my players crash on sending client info, only on my server
Here is the crash dump : http://dumps.metastruct.uk.to/dumper.py?dump=hl2_170801_crash_2017_10_23T21_20_38C0.mdmp

Sorry for my bad english ^^

It looks like CAC Anticheat and ACrashScreen are conflicting with each other. Are you using a legit (non-leaked) version of CAC Anticheat and ACrashScreen?

I do not use any leak, i use old version of ACrashScreen because the newer dosen’t have chat
I will try to remove ACrashScreen thanks you
