by the way, this 2 confs are not exist in paperless, or they are very old.

correct is:
PAPERLESS_EMAIL_TASK_CRON=*/30 * * * *

https://docs.paperless-ngx.com/configuration/#PAPERLESS_EMAIL_TASK_CRON

so i think your system is outdated, check your conf

I did that already a few times.
I removed the 2 lines:

PAPERLESS_ENABLE_MAIL_FETCHER=1
PAPERLESS_MAIL_FETCH_INTERVAL=300

and added

PAPERLESS_EMAIL_TASK_CRON=*/30 * * * *

Seems there is no "/opt/paperless/data/celerybeat-schedule.db" to begin with, i will try to rename the db file to only have 1 extention instead of 2.

Recap:
The service wouldnt start because of possible corrupt /opt/paperless/data/celerybeat-schedule.db.
The file "/opt/paperless/data/celerybeat-schedule.db" didnt exist but the file "/opt/paperless/data/celerybeat-schedule.db.db" did.
I did not manually change the file name, so this should have happened durring upgrades/updates of paperless-ngx using the "update" command in the console.

Running the below commands, removing the file with the duplicate extension and recreating the database file fixed the issue. of the schedule service crashing and not running.

systemctl stop paperless-scheduler

Yes, still waiting for the schedule to import mail though.
I think it should be noted that somehow the database file ended up as "celerybeat-schedule.db.db"

Update:
Mail was still not being processed.

Removed the line: (cron job that sets the check to every 30 minutes)
PAPERLESS_EMAIL_TASK_CRON=*/30 * * * *

Then removed the database again:

systemctl stop paperless-scheduler
systemctl stop paperless-consumer
rm -f /opt/paperless/data/celerybeat-schedule.db

Did a full reboot. Database got recreated by the service.
This fixed the issue. Mail attachments immediately started flowing in again and uses the default schedules.
