Composer can't upgrade drupal from 10.0 to 10.1 - "it conflicts with another require" with no additional information

For support could you please share a composer.json file that exhibits the issue?

I've been having the same issue with drupal/rdf, drupal/classy, drupal/color. Still having the issue now that I'm trying to upgrade to 10.2.2

@chambers Precisely what is the command you type and what, in full, is the output?

What is the Composer version?

Composer version 2.6.2

Upgrade to 2.6.6 and try.

The composer upgrade fixed the issue for me.
