EF44 restarts every minute and becomes unresponsive

Hi,

I just received my EF44. When trying to use it (in Ableton) or set it up (in Grid) editor, everything works fine for approximately a minute, then after a minute the EF44 crashes with a green light flash, goes back to blue then becomes unresponsive (detected in Editor but knobs/fader don’t change value + detected as MIDI in ableton but not receiving MIDI signals)

I’m on latest firmware : 1.2.36
Latest editor version too : 1.3.3
