Driveshaft/circlip sounds possible and is quite common, also check fluid levels in the shared brake/clutch reservoir at the front of the car as low levels can cause clutch/engagement issues ...
Also I believe the slave cyclinders are prone to leaking and losing fluid/contamination but this is inside the bell housing so the clutch would need to be done anyway as it's a gearbox off job.
