C_BaseCombatWeapon::GetCSWeaponData(...) returned nullptr.

[ghost]

I've been able to reproduce this crash with a fresh git clone of the repo.
Attempting to use IsGun, IsRifle, ... causes a crash due to GetCSWeaponData returning nullptr.

Maybe you should check if the weapon you are calling GetCSWeaponData exists, in other words if it isn't a nullptr. For example if you want to call GetCSWeaponData on your current local player's weapon you would do it like this:
auto weapon = g_LocalPlayer->m_hActiveWeapon(); if(!weapon) return; // or you can also use if(weapon != nullptr) return; which is the same thing // call whatever you want after you checked the weapon for a nullptr.

I have a check, if (!weapon) return; and I am able to get the weapon's spread somewhere else in my code so I don't think my weapon is nullptr.

I'm having the same issue, generally issues with weapon data just randomly crashing

I'm a bit late to the party, but I'll give it a shot: has anyone achieved a more or less ghetto fix?

CCSWeaponInfo* GetCSWeaponData() { if (this != nullptr) return g_WeaponSystem->GetWpnData(this->m_iItemDefinitionIndex()); }
Not a great solution, but works.

Well it kinda works but not really. I mean it helps to prevent csgo from crashing but it still doesn't always return corrent WeaponData. For some weapons I don't get any Data, for some wrong and for some the correct

@CodingTimeDEV Have you been able to fix this issue?
[EDIT]
I found out that if I will join the Aim Botz - Training map and then go onto other maps it won't crash anymore. Possible that it's maybe just a command in-game that's causing it to crash?

I'm kinda late but i found the issue.
In NETVAR(int32_t, m_iItemDefinitionIndex, "DT_BaseAttributableItem", "m_iItemDefinitionIndex"); (csgostructs.hpp) change int32_t to int16_t
