Just departed EGGW to EGNX. Was climbing through FL100 to FL120 and just done a direct too UPDUK. I was clearing out the way points when all the systems just froze. Screenshot attached. Aircraft flew normally with manual thrust and control however nothing else would work but the altimeter. Photo attached. 

I just had this too, everything apart from the altimeter froze and the left fmc went blank. Happened when I was clearing waypoints as well. Hopefully there's a quick fix to it. I was using the PW engine variant.

Yes, we're looking into these WASM soft-crashes. Thanks!
