UI freezes since @ngx-matomo is added

Since we added @ngx-matomo/tracker to our platform our UI completely freezes and becomes unresponsive when clicking on kendo-ui elements. Before the Matomo script, this was never an issue. What could cause this?
using: https://github.com/EmmanuelRoux/ngx-matomo
but the error seems to originate from within the matomo.js script that is loaded from the cloud, although this is unclear because the browser tab completely freezes.
