The menu bar builds Type > Font in every frame, the first included, and
its family list waited for the scan of every installed font. When that
scan took longer than the 20 s first-frame watchdog (thousands of fonts
on a slow disk, or each file checked by antivirus), the app took the
graphics adapter for hung and started again without it, until none was
left and no window ever showed.
The menu now lists the fonts already loaded until the scan ends, then
all of them (FontDb::menu_family_list_now, installed_fonts_ready).
