Hi, I pasted the script and now I can't log into my server. I edit pos players and delete npc lua/xml and nothing, what could have happened?

LUA:

dofile('data/npc/lib/npcsystem/npcsystem.lua')

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

local guard = defender:new()

guard:setHitInterval(getNpcParameter("HitInterval"))
guard:setShootEffect(getNpcParameter("ShootEffect"))
guard:setHitEffect(getNpcParameter("HitEffect"))
guard:setTypeDmg(getNpcParameter("TypeDmg"))
guard:setDamage(getNpcParameter("minDamage"), getNpcParameter("maxDamage"))
guard:setSayText(getNpcParameter("sayText"))
guard:setHeal(getNpcParameter("minHeal"), getNpcParameter("maxHeal"))
guard:setHitSkulledPlayer(getNpcParameter("hitSkulledPlayer"))
guard:setMultiAttack(getNpcParameter("multiAttack"))
guard:setDmgRadius(getNpcParameter("dmgRadiusX"), getNpcParameter("dmgRadiusY"))
guard:setHealRadius(getNpcParameter("healRadiusX"), getNpcParameter("healRadiusY"))

I add, GUYS I reinstalled the database from my backup and the whole engine and client, I also tried to change the map and I still can't log in. What happened? It throws me the tibi client, it even freezes it and I don't want to go any further.

Can you at least say us errors you are getting?

ImaG · May 26, 2025

I reinstalled everything // engine, database, client // moved to tibia.spr/dat items.otbm and still nothing so I started digging in the documents and found the error FILE_IN_CAB: otclient_dx.exe.29372.dmp so I read this error through the tool and got a critical error: ExceptionCode: c0000409 (Security check failure or stack buffer overrun)
Subcode: 0x5 FAST_FAIL_INVALID_ARG log critical error
