kemper crashes at startup on creating cache data for presets

hi, this happened to a friend and he has tried anything, (holding rig, system, quick, < > with the new firmware) but his kemper still crashes at startup

I noticed in a video call that his kemper is starting up but crashes at "creating cache data for presets", looks like something is wrong with his presets

anything else he could try? thanks!

Nvm my friend fixed it, he did hold the left button on top of the screen when turning his kemper on and he was able to reboot his kemper and reinstall the last firmware
