SSRS 2019 Shared Schedules Expire Before Expiration Date - reporting-services

Question

We have several shared schedules on an SSRS 2019 server that keep failing. I have tried removing the end date and changing the end date to different dates in the future.
We have found scripts that show us the scheduled job ID so we can look at the job on the server.
What else should we be doing to help find the cause of this?
I'm not sure if this error is related. The job ran this morning at 6am and expired some time after (but I don't know how to tell exactly when). For the error related to the user account, this user has access to the report and is active.
