Can we see the an example of the complete HTTP response? Wrap code output in
<code>
, which is needed here to render formatted output properly.I can't reproduce this on a new Drupal install with https://simplytest.me. The output is well-formed.
Add to the issue summary complete steps to reproduce that you verified beginning with installing Drupal 10.
Thank you @cilefen for looking into this and showing me this website to help with debugging. I was able to narrow down the issue being caused by my custom theme, which later I was able to narrow down the problem being a blank line in my .theme file which i thought was empty. As soon as I removed the blank line everything works.
