Stuck Clutch 1995 Alfa Romeo 916 S 2.0 l TS

I bought a Alfa Romeo 916 and knew I would have to do some work on it, including replacing the clutch. I bought a LuK clutch and replaced the clutch plate, pressure plate, and throwout bearing (Flywheel was fine, no grooves or pitting or obvious signs of wear). Since putting the gearbox back on and reconnecting the clutch line / hose to the slave cylinder the clutch is stuck in the disengaged position (I think. Easy to spin wheels by hand when in gear.) I have looked at the master and slave cylinders and can’t see any sign of leakages, and the reseviour still has oil in it. The clutch line / hose is a little deformed as I accidentally bent it when removing the gearbox, I have heard this could be the cause of the problem, but I’m not sure.

Unfortunately the clutch kit did not come with an alignment tool and I was unable to find one (I live in Switzerland) so I had to make do using a socket extension, dowels and masking tape to make a very tight fitting tool. I think I had the clutch plate aligned properly as the gearbox went back onto the engine with no problems.

What may be the cause of this issue?

Milage: Approximately 200000 Km

Thank you very much.
