[fixed] emulationstation segfault on RPI4 fresh install

[geoff1]

Hi,

I've been having a weird problem with retropie today. On a new flashed SD card with Pi4 1gb, system boots and configures a joypad, then the UI loads but as soon as I tap configure I get the message "Emulation Station crashed!" and then dropped back at the command prompt.

md5sum is correct and reflashing made no difference.

Heres the gdb backtrace:

I did manage to get past this error by running apt updating the entire system and then doing sudo ~/RetroPie-Setup/retropie_setup.sh and choosing to upgrade everything possible. I didnt take notes so not sure which component upgrade fixed things but after updating and rebooting retropie worked as usual.

Hopefully that helps someone out...
