Problem/Motivation
I am using Scheduler version 1.4.0 and Scheduler Content Moderation Integration 1.4. I want to update both to ^2.0. I was unable to upgrade either module due to composer conflicts with each other's versions. There is a deadlock where Scheduler wants a higher version of SCMI, and SCMI wants a higher version of Scheduler. The solution I came up with was this: composer require 'drupal/scheduler_content_moderation_integration:^2.0@beta' 'drupal/scheduler:^2.0'. This allowed the modules to be upgraded.
However, it crashed our site. Oddly, on a test site, there was no issue. On production, the site crashed with this error:
The website encountered an unexpected error. Please try again later.

I'm not sure what to do now. I hope this error provides clues.
Steps to reproduce
Using Drupal 9.5.10, with the module versions shown above. Try to update either module using composer. I was unable to do this. By adding them both to the same composer require command, I was able to upgrade. This crashed my site completely. No page was accessible at this point, so I downgraded back to previous versions.
