This. Usually you should replace both at the same time. Sounds like you need a new master cylinder.
Also, when you bleed the clutch, the pedal isn't supposed to come back up on it's own. You need to reach down and pull it back up. When you open the bleeder valve, it releases the pressure built up so there is no more pressure to push the pedal back up.
If the clutch fork isn't moving, it could be a few possible things. If a new MC and bleed doesn't work, you'll probably have to pull the transmission off and look at the clutch fork and throwout bearing itself.
My clutch fork went bad last year. The clutch fork has a dimple that pivots on a metal ball inside the transmission case and mine was completely worn through so it was BARELY pivoting. Enough to disengage the transmission but not enough to let me change gears. I drove my car clutchless over a total of like 15-20 miles lol. Starting from stops, upshifting, downshifting...it was actually fun lol.
