No, the clutch would freeze closed, not open (unless you jammed the pedal
down with a stick when you put it in storage) . Sounds like a complete
absence of fluid to me, possibly coupled with a broken/missing pedal return
spring (possibly missing for some time). Looks like a master/slave rebuild
in your future.

Failure to engage is not a usually a symptom of hydraulic problems (sounds
like your mental model of this whole system is backwards, based on the two
questions). It sounds more like the clutch disc is worn out, or there is a
problem with the clutch diaphragm spring and/or throwout bearing, or oil on
the clutch from an internal leak (rear main seal). I suppose an internally
collapsed hose could do something like that, but this problem is more
commonly encountered with front brake hoses, where piston return is
dependent on the relatively wimpy forces of piston seals and runout, not on
clutches where a massive diaphragm spring is applying the return pressure.
Does the pedal pump up? Is there noticeable oil/fluid on the bottom of the
bell housing?
