Uncaught TypeError: $(...).once is not a function with Drupal 10

Hello,

I am working on a Drupal 10 (10.0.2) project and I have problems when I load forms (node/add, for example) with Boostrap theme enabled. There are some js errors:

drupal.js?v=10.0.2:64 Uncaught TypeError: Cannot read properties of undefined (reading 'chain')
drupal.js?v=10.0.2:64 Uncaught TypeError: $context.find(...).once is not a function
...

You can find all of them in the attached image.

Errors appear both in the main theme and in the subthemes created with the starterkit.

Could somebody help me?
Thanks!
