did you try something like this?

local ADDON_NAME = "YourAddon"
 
local function GetAddOnVersion()
    local addOnManager = GetAddOnManager()
    for i = 1, addOnManager:GetNumAddOns() do
        local name = addOnManager:GetAddOnInfo(i)
        if name == ADDON_NAME then
            return addOnManager:GetAddOnVersion(i)
        else
            d("addOnName has not been found")
        end
    end
    return 0
end
 
d(GetAddOnVersion())
