Check to see if the cable moves freely with the clutch arm disconnected. My kit came with a frayed cable brand new, and it stuck inside the jacket.
Walmart sell packs of asst. cables for under $6.00.....

Maybe the little pin that hold the clutch actuator in place is broken or fell out. Can you just slide the clutch arm out of the cover?

Take the clutch cover off, pull the pin out (in the center of the sprocket) and stick a magnet in the hole to see if the ball bearing is inside there. It should come out with a magnetic pickup, or maybe just lean the bike over and it might roll out. I dont see how you would lose it while riding though, maybe just need to adjust the star nut on the opposite side, turn it in a notch or two...

I'm thinking the cable end just slid a little and when you pull in the clutch, it's not moving the arm enough.

After running the motor for a while, my cable would heat up and the clutch would no longer fully disengage. Could be something like that happening to you.

I never actually fixed it, I had that problem right up till the motor bit the dust. Pretty sure the cable would heat up to the point where it would "give" a little and so not as much tension would be on the clutch arm. I will be getting a new clutch cable to correct that issue though.

I don't think that big spring is much of a heat shield.
