I'd say that this may be an issue with the clutch 'delay valve'
this is a little sprung loaded restrictor thats plumbed in line and should look something like this plastic part in the image
I've known them to stick over time and I'd suggest to remove it altogether and see if this improves things
its possibly related to heat as if the clutch plate is slipping and overheating things then it will all expand and possibly lock up
and I would recommend to remove the delay valve as its only there to help with pedal feel and isn't required for clutch function but it can fail and prevent proper operation
do you still need help?
