Two suggestions with questions: 1. Is there a way you could display the image from one of the Xubuntu 20.04 computers to the Xubuntu 18.04 computer then from that computer to the other one? Try doing that.
2. Did you install digikam from here: https://snapcraft.io/digikam? If not try that, but you may need to uninstall the one you have first. Contact the developers also.
