It looks like the issue is related to the misspelling of the jarallax variable that should be _jarallax:

_proto.destroy = function destroy() {
      _previewCollection2.prototype.destroy.call(this);

      if (this.element) {
        jarallax(this.element, "destroy");
      }
    }

to

_proto.destroy = function destroy() {
      _previewCollection2.prototype.destroy.call(this);

      if (this.element) {
        _jarallax(this.element, "destroy");
      }
    }

Hello @andrewdaluz ,

Thank you for your report and collaboration.

We attempted to reproduce the issue in version 2.4 develop but were unable to do so. Attached the screen recording for your references.

Steps to Reproduce:

• Login to magento admin
• Go to a product edit page on admin
• Edit the description field with Page Builder
• Add a new empty row
• Save the product
• After the page is reloaded, try to edit with Page Builder and remove the empty row
• Save the product (after the row is removed)

We followed these steps and did not encounter any errors. Could you please recheck the issue in the latest version? Alternatively, let us know if we missed any steps while reproducing the issue.

Therefore, we are marking this ticket as "Needs Update."

Thank You!

Interesting. Might that be a Firefox or Chrome tests?
The issue is on https://github.com/magento/magento2-page-builder/blob/develop/app/code/Magento/PageBuilder/view/adminhtml/web/js/content-type/row/preview.js
You can see that the variable in the function (_jarallax) while in the scope of the function it's been called as jarallax() and not the _jarallax() method.
