I have ran into an issue with Rapid Photo Downloader being unable to scan SD cards. I reported the issue to the RPD team here: Bug #1907943 “Device scan failed with pymediainfo 5.02” : Bugs : Rapid Photo Downloader
The dev informed me that it is due to the current version of pymediainfo and suggested I report to Manjaro devs that pymediainfo be updated to 5.0.3 as soon as possible.
