It seems to be an import pipeline bug.

Photos does a lot of extra work on import (merging RAW+JPEG pairs, generating previews, database indexing, optional deletion), so my guess is a concurrency bug where a buffer gets reused or a file handle is closed before the copy finishes.

Rare, nondeterministic corruption fits the profile.

This is also my guess. It's really a bummer, and I'd report it to Apple but since it's nondeterministic I have no idea how to provide repro steps.

You don't need repro steps if Apple is serious about quality. Just the description of what's happening should give enough to a senior Apple engineer to intuit where this is possibly happening and create tests that will stress their software to repro this.

I see you've never used Feedback Assistant
