This is very strange…
Is this the pop up that is shown in your website?
What did you configure in your MTM? How are you hosted?

The source of Matomo Tag Manager never contains alert, so I doubt that’s what creates the alert-window.

Maybe the code loaded by the tags creates it.

You can see the JS those two tags execute here:

github.com

matomo-org/tag-manager/blob/4.x-dev/Template/Tag/FacebookPixelTag.web.js

(function () {
    return function (parameters, TagManager) {
        var setup = {};
        var isLibLoaded = false;
        this.fire = function () {
            if (!isLibLoaded) {
                isLibLoaded = true;
                !function(f,b,e,v,n,t,s)
                {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
                n.callMethod.apply(n,arguments):n.queue.push(arguments)};
                if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
                n.queue=[];t=b.createElement(e);t.async=!0;
                t.src=v;s=b.getElementsByTagName(e)[0];
                s.parentNode.insertBefore(t,s)}(parameters.window,parameters.document,'script',
                'https://connect.facebook.net/en_US/fbevents.js');
            }

            var pixelId = parameters.get('pixelId');
            if (!(pixelId in setup)) {
                setup[pixelId] = true;

Alert is for google analytics ID, issue was caused by google. It’s not related to MTM, somehow replacing GTM with MTM has activated old JS.
