Matter (most probably) solved.
I am using a tool that firmly assigns drive letters to USB drives (USBDLM)
Within the settings of this tool, drive letter "J:" , the conflicting one above, was assigned to a virtual container.
When the virtual container is -not- mounted, then Windows releases that drive letter as being free.
The USB thumb drive then takes that drive letter.
However, this is in conflict with USBDLM, that is trying to assign the drive letter to a (non mounted) virtual drive.
Process of mounting, unmounting, mounting, unmounting... starts.
I have removed this drive letter from the USBDLM settings.
This time cCreating a rescue disk went fine.
Curious thing though is that I have this setup for years and never encountered problems.
OTOH It could be that, by mere coincidence, Macrium selected another drive letter those cases... I don't remember.
Anyway, it looks like the matter is solved.
Sorry for the confusion.
