You can scan directly into Gimp with SANE and xsane installed but in Gimp xscanimage is used.
It does look like there is a bug with the xsane Gimp plugin.
To use xsane I have a replacement that I use with kubuntu 20.04
File attached, unzip, put it into your Gimp plugins folder /home/your-login-name/.config/GIMP/2.10/plug-ins/ (aka ~/.config/GIMP/2.10/plug-ins/ )
Proof that it works: https://youtu.be/V87concrL1U about 5 and a half minutes duration.
