I had this issue recently.. patch and instructions above worked for me with Drupal 9.5.10 and Diff 8.x-1.1

I encountered a bit similar issue with a multisite.
I did the following steps which caused the error.
1. Enabled Diff and configured it in site A.
2. Exported all changed configs with drush cex.
3. Copied the new configurations to a site B
4. Run drush cim which enabled Diff and imported the related configs.
5. When trying to compare revisions, I got the same error as in this issue.Also the settings page for Diff was broken and it was missing all the needed settings. In my case I was able to fix it by removing the configs and importing configs again which uninstalled Diff. After that I was able to install the module with Drush and all the settings appeared correctly.
It seems like installing the module from configurations is missing possible some database update step.
