Looks like even the left main gave way.
All hydraulics I have ever used eventually bleed off, some are veeeery slow, and need to be protected by locks to sustain position.
I guess there is a perfect seal somewhere but I have never seen it in an elastomer. Metal to metal yes, multiple stack PBR usually and amazing they do.
The left wing drop was secondary, likely from the plane lurching forward and the mains being chockd. In this 13 second video clip, you can see the nose gear fold forward as though unpinned, and not a hydraulic leak.

That is why you never trust hydraulics if you have to work under any part of a machine. It should always be cribbed up.
