OBSERVED RESULT

A generic error displayed ("could not connect to scanner" or similar) and you have to quit the app.

Linux/KDE Plasma: Manjaro KDE Edition
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.10

ADDITIONAL INFORMATION

If you initialise the scanner by starting e.g. VueScan (free demo available at https://www.hamrick.com/ and in AUR/pamac as package "vuescan-bin") and THEN start scanlite, it works as expected.
