Hyper Backup stuck on canceling

I have had my hyper backup up and running. Today I found it was taking a long time to check the size for scheduled backup so I pressed cancel and now it’s stuck on canceling. Is there a solution to this? I’ve tried a restart but the synology said there is a hyper backup tasking running and that I have to suspend or cancel before continuing.

thank you for your help

Cancelling takes a long time with HB, this is normal.
