Open RAW file from Olympus new camera OM-1

You have posted in the Photoshop Elements forum.   Are you asking for confirmation or are you here to complain?

You seem to be correct.  Adobe's list of supported Camera Raw cameras does not include the OM-1.   I would expect an update to Camera Raw (for Photoshop CC and Bridge) to be released soon.  I don't know, but it is unlikely that a further update to Photoshop Elements 2022 will be released.  But there may be a workaround once the full Camera Raw is updated.
