Summary of the issue you are facing:
I’m getting the following error over & over again:
RuntimeException Error during request to Context Chat Backend (ExApp): ExApp context_chat_backend not found
Error while running background job OCA\ContextChat\BackgroundJobs\ActionJob (id: 14579, arguments: null)
After reading the external app instructions, I do not want to use the Chat app or external apps at all at this time. How can I clear out these errors and stop them from recurring?
Steps to replicate it (hint: details matter!):
It’s been happening since I installed the Nextcloud Assistant

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):
