SUMMARY
After updating to Plasma 6.3 Beta and Qt 6.9.0 Beta 1, Inkscape fails to start with the following error:

(org.inkscape.Inkscape:139074): Gdk-WARNING **: 11:24:08.323: Native Windows taller than 65535 pixels are not supported
(org.inkscape.Inkscape:139074): Gdk-CRITICAL **: 11:24:08.357: ../gtk/gdk/wayland/gdkdisplay-wayland.c:1353: Truncating shared memory file failed: Invalid argument
(org.inkscape.Inkscape:139074): Gdk-WARNING **: 11:24:08.365: Native Windows taller than 65535 pixels are not supported
(org.inkscape.Inkscape:139074): Gdk-CRITICAL **: 11:24:08.369: ../gtk/gdk/wayland/gdkdisplay-wayland.c:1433: Unable to create Cairo image surface: invalid value (typically too big) for the size of the input (surface, pattern, etc.)
[1]    139074 segmentation fault (core dumped)  inkscape

I attach the full backtrace.

I don't think is an Inkscape bug since it was working just fine with Plasma 6.2 and Qt 6.8. Also, it looks like it crashes because a wrong window size is given.

STEPS TO REPRODUCE
1. Update to Plasma 6.3 and Qt 6.9
2. Try to start Inkscape

Inkscape crashes, but all Gnome apps do not work correctly either. I have tried Gimp and Gnome Console.

If anyone ends up here. This was the actual bug affecting me:

Solution was cleaning font cache with: fc-cache -f -v
