Help with detecting Character?

I get 2 errors in output:

attempt to index nil with Parent - Line 6

and

Argument 1 missing or nil - Line 12

I have no idea how to troubleshoot these errors and I need assistance with them if possible.

Code:

local Player = script.Parent.Parent.Parent
local Char = Player.Character
Char.Hitboxes.Part.Touched:Connect(function(inst)
    if Char.Hitboxes.Part.Active.Value == true then
        local player
        if game:GetService("Players"):GetPlayerFromCharacter(inst.Parent) or inst.Parent:FindFirstChildOfClass("Humanoid").Parent.Name then
            player = game:GetService("Players"):GetPlayerFromCharacter(inst.Parent) or inst.Parent.Name
            else print("no")
        end
        --------
        local Character
        if player.Character or game.Workspace[player.Name] then
            Character = player.Character or game.Workspace[player.Name]
        else print("no")
        end
        print(Character)
        print(Player.Name .. Player.Parent.Name)
    end
end)

Change

if Char.Hitboxes.Part.Active.Value == true then

to

if Char.Hitboxes.Part.Active.Value == true and inst ~= nil then
