Sorry, but I don´t know how to produce and where to find a stack trace. Although I am a developer, I am not a drupal developer. I tried adding the Devel module, but did not see what extra information that gave me.
I think the only other interesting modules that I use are 'Content Moderation' and 'External Authentication'.
I encounter this same issue with Oidc 2.2.0 under Drupal 10.
When I try to logout, that doesn´t work. I had to remove all cookies from the website in my browser to logout.
The logs have a warning
type: Access Denied
location: https://mysite.org/oidc/logout-redirect?check_logged_in=1
