inav-configurator 8.0.0-RC1 is persistently opening Save to File in the users $HOME path. And, after the first Save to File attempt each new attempt to Save to File is silently opening the save browser in the background.
This is observed in ubuntu 24.04 running from nightly builds last week and the 8.0.0-RC1 asset INAV-Configurator_linux_x64_8.0.0.deb.
Reverting to INAV-Configurator_linux64_7.1.2.deb returns the behaviors of opening Save to File in the most recently utilized path and opening each attempt in a foreground window.
