srcds crashing on map change and using SM

[Raiden50275]

Hi, as soon as i updated to the latest update the server and my steam client started behaving starngly :

server :
crashes once i change the map or toggling the sm_admin menu. removed sv_lan from server.cfg and now i can change the map using commands but still crashes when opening the admin menu (SM).

Client :
When Creating a lan server and changeing map (changelevel) to any map it crashes.

the error is the same Hl2.exe not responding or srcds.exe not responding.
