jQuery is not defined joomla

Question

I have a code for the anime of my joomla site using jQuery, however I noticed by the inspector that a few days after the php version update, these animations stopped working and this error appeared. I have tried returning the old version but the error persists. This is one of the snippets of my code that has this problem. I wonder if you have any other way to declare this jQuery.

t.fn.spbalert = function (e)
{
    return this.each(function ()
    {
        var n = t(this),
            s = n.data("sppb.alert");
        s || n.data("sppb.alert", s = new i(this)), "string" == typeof e && s[e].call(n)
    })
}, t.fn.spbalert.Constructor = i, t.fn.spbalert.noConflict = function ()
{
    return t.fn.spbalert = n, this
}, t(document).on("click.sppb.alert.data-api", e, i.prototype.close)}(jQuery),
