Just some limited searching seems to indicate that the "gtk" widget
style was dropped around Qt 5.7 or so. Maybe you're running a newer
version of Qt and you are requesting the gtk widgets?

See post #36.
All the trails are from 2016/2017, though. Not sure they are
relevant today.

The problem seems to be something to do with "GtkWidget" (see below).
24.06 built fine from git source.
I have recently upgraded to fedora 39 and this is probably the first
time I have tried to
run RG since. Same result on a similar/identical system.
gtk3-3.24.41-1.fc39.x86_64
gtk4-4.12.5-1.fc39.x86_64
RG output:
