Error in URLEmbed constructor when alternative cache modules enabled

Thanks for reporting this. I am unable to reproduce the problem using a standard Drupal installation of 10.3 with the 3.x branch of this module. Below are the steps I took. Can you provide more specific steps to reproduce this problem? (Please make sure this problem occurs with a standard Drupal installation without any other modules first!)

1. Install the "standard" installation of Drupal.
2. composer require drupal/url_embed:^3
3. Enable the url_embed module.
4. Add a "Link" field to the Basic Page node type.
5. Set the field formatter to "Embedded URL"
6. Add a Basic page node and populate the Link field with a valid embeddable URL. -- no problems.
7. Add the URL Embed button to the "Basic HTML" text format and enable the "Display embedded URLs" text format filter.
8. Create a Basic page and use the URL Embed button in the CKEditor 5 toolbar to embed a URL -- no problems.

In your steps
add redis or filecache modules
Enable them
the error occurs.
