Question about GMC R3500
It is very possible that the operation for the clutch has failed
as to hydraulic or cable , all you have to do is look under the bonnet and see if there is a clutch master cylinder or a cable from the clutch pedal
if hydraulic replace the clutch master cylinder and slave cylinder and if cable replace the cable
better still take it to an accredited clutch and brake service center and have it properly diagnosed service

If the car hasn't been driven for a while it could be corrosion on the fork but I think that is unlikely. I think you are right about the release bearing being jammed in the spring. If the truck has quite high mileage, it probably means a clutch job.

It is very difficult for you to disengage the clutch by hand or with any leverage you can get outside the transmission. There is over 200 lbs of force clamping on the clutch disc.
If you replaced the clutch and took the slave cylinder out of the transmission without putting a brick under the clutch pedal or disconnecting the pivot arm from the pedal then you ruined the hydraulics. Buy a new PRE-BLED system from a local auto store. Generally this is the problem.
Either that or the clutch fork is bent or you installed the throwout bearing backwards (or simply fell off the fork which is not all that uncommon).
