Regrettably, no, not a success.

It is curious behaviour, at least the workaround of copy paste to a new directory solves it now for the edits I wish to do, but why it does it to some files and not others I have no ideas. Probably Windows...

Reinstalled XNViewMP, remembered to run as Admin the first opening.

Restored most HEIC files opening internally from thumbnail.

Some still randomly don't. XnViewMP triggers a download of photo file from OneDrive. On some photos (slow download? processing error, metadata error? speculation ...

WIndows 10 latest updates, x64

After installing XnViewMP 1.0.0 opening up a thumbnail of a new HEIC file from phone results in it opening in the windows Photo app and not within a tab inside XnViewMP.
