My bike does that too. My work around is to roll down my driveway clutch in, then shift into 2nd.
That breaks the plates loose, back to first and off I go.

If the cable, worm gear and pushrods are moving freely, I would pop off the tight case cover and have a look - meaning disassembly. It’s pretty easy to do. Clean everything up, inspect for wear and reassemble and adjust. I’d replace the friction plates if get look or measure to be worn.

What oil are you using and where are you located?

Using 20w50 non synthetic oil located in east central South Dakota I had replaced the sump plate gasket and it sat for a week or two after that it was the clutch was stuck freed it up and a week later it was the same way. Not sure if the clutch basket has wear ridges keep the plates from separating

I’d imagine it’s cold where you are. 20w50 in cold temps will cause your plates to drag. Ridges on the basket may cause erratic operation, but if the plates were hanging up on ridges that badly, I would think you wouldn’t be able to squeeze the lever.

Sometimes for a lark I’ll get on the bike, pull the clutch lever in and then cycle the kick start (with no intention of starting her up at the moment).
First kick has resistance, second kick has less and then the third will spin freely telling me the plates have separated.
