I'm on windows 10 I'm running PM6+ version 6424.
My workflow hasn't changed recently.
My raw files are orfs from either an Olympus EM10 II or EM5 III. The raws are developed in rawTherapee. They come out of rawTherapee without any metadata. I restore the metadata using tools / update IPTC/XMP from raw. This is not working today. I updated PM6+ this am.
Here is a jpeg I can't update.
