Can anyone help me with any ideas about what the problem might be if it's not the module?

I think it's my theme because I'm using the module on another site and I'm not having the same problem.
What can I check?

Thanks

After long hours of research, I discovered that it was my custom theme. In the web console, I got a message saying "drupal.ajax is undefined."
When I created my theme over a year ago, I made a copy of the Olivero theme. Mine worked fine, but there must have been some Drupal 10 updates that weren't reflected in my theme. I searched and couldn't find anything, so I started with a new version of the Olivero theme.

After making a copy of the new version of the Olivero theme and adapting it to my design, my theme works fine, and there are no more JavaScript aggregation issues.
