Random images mysteriously going missing from website

We’re running Beaver Builder on our site. We have had at least 10 - 12 images seem to delete themselves from the media library and vanish. This has been happening over 6 months or so… at first I would spot a missing image and think I’d simply accidentally deleted it, but I now realise it’s an ongoing issue. There seems to be no logical reason as to why one image is missing and another is not. It’s happening to images that have not been updated or touched in any way.
Has anyone else had a similar experience?
