Raised an MR for one possible approach to this.

how is the uninstall managed?

this worked for me

Also seeing this, saving the form at admin/config/people/accounts doesn't work even after uninstalling this module.

Using v 1.4 of this module.

I applied the changes above to the module, uninstalled the module, and this allowed me to then save the form at admin/config/people/accounts.

For anyone who has installed this module before applying the patch above.

I managed to fix this by deleting these 2 lines from config in system.site.yml:

site_disable_page_node: true
site_disable_page_node_404: false

So I did a config export, deleted these 2 lines, then did a config import.

This could also be added to the .module file to handle this when the module is uninstalled:

/**
 * Implements hook_uninstall().
 */
function disable_page_slash_node_uninstall() {
  // Load the system.site configuration.
  $config = \Drupal::configFactory()->getEditable('system.site');

  // Remove the unwanted configuration lines.
  $config->clear('site_disable_page_node');
  $config->clear('site_disable_page_node_404');

  // Save the updated configuration.
  $config->save();
}

Yes indeed, that was mentioned by @SocialNicheGuru and I missed the update, ill get a change in to cover this

Works for me, thanks Aaron!
