After upgrading to Drupal 9.0.7. I am getting the following message in the browser console when clicking the back to top button. The button does not work:

jquery.min.js?v=3.5.1:2 Uncaught TypeError: S.easing[this.easing] is not a function
    at init.run (jquery.min.js?v=3.5.1:2)
    at u (jquery.min.js?v=3.5.1:2)
    at Function.S.fx.tick (jquery.min.js?v=3.5.1:2)
    at st (jquery.min.js?v=3.5.1:2)

Jquery version seems to be the same as drupal 8, so i'm kind of at a loss here.

Same problem on the same Drupal version. The solution above unfortunately crashes the site.

@nikhitarathore Same =( I'm running Bootstrap Barrio. Maybe those are incompatible or something.

#2 Works for me.
Drupal 9.0.7 with a custom Bootstrap-based theme.

Thank you @nikhitarathore

jquery ui is deprecated in 9.x which is why this module doesn't work (see https://www.drupal.org/node/3067969)

A work around is to install the jquery_ui_effects module and add the dependency "jquery_ui_effects/fade" to your theme's libraries.yml file.
