Plane systems crash when changing runway after auto landing engaged

[lfrivera]

Hello, 

Today I was landing RWY 04R in LFMN with AP1/AP2 APP engaged. Planed was landing in autopilot. I decide to change to RWY 04L in FMC during approach (after ATC last minute change).

When I input change in FMC all the plane systems crashed. No physical or digital button was usable. 

I'm creating this thread so you can investigate? 

Thanks.
Luis
