takie błędy nie powinny występować bo jest is_user_alive
możesz spróbować zamienić to linijkę

if(is_user_alive(host) && g_bPlayerInvisible[host] && host != ent && is_user_alive(ent) && cs_get_user_team( host ) == cs_get_user_team( ent )){

na

if(is_user_alive(host) && g_bPlayerInvisible[host] && host != ent && is_user_alive(ent) && pev_valid( host ) && pev_valid( ent ) && cs_get_user_team( host ) == cs_get_user_team( ent )){

lub może jakiś inny plugin koliduje z invis wyłączaj je po kolei aż ustalisz który to
