G1 shut off during dive

My brand new G1 solar just shut off during a freedive to 20 meters in freshwater.

Two days later the same happened to my friends G1 non solar.

Both watches just shut off, forgot the dive data of the last dive and could easily powered back on.

Posting it on reddit and found another stranger who claimed the same happened to them during a scuba dive.

Anyone else ever encountered something like that?

I mean wtf? I can understand a faulty product and hardware failure but this seems to be software related and is extremely worrying for a dive computer.
