The file does have a 'meta' box, and I can open it in Photoshop.

I do not know why you are getting an error message, it may just be some kind of random glitch.

Can you open this file using libheif-sharp ? The problem occur with all files created on macOS. But I can open this file on Linux using libheif.

No, it fails with the missing 'meta' box error.

I found the issue, my file reading code was validating parameters in the wrong order. The output data pointer can be null for zero-byte reads.
