There is nothing to do 😕 The problem come from the ES conception. A work of optimization has be done by @retroboy in recalbox 4.0.0 to multi-thread the loading/writing process. So you'll have this problem with all other distributions using ES as frontend and shutting down it cleanly. If you want to get back your recalbox responsive, you must no more use scrape or scrape less roms/systems. To clean up your gamelist data, you must kill ES before working on these files. To kill ES, F4 with a keyboard plugged on recalbox, or one of these commands by ssh : killall emulationstation or /etc/init.d/S31emulationstation stop. Once done, reboot or /etc/init.d/S31emulationstation start.
