Clutch won’t disengage after start

[SDC84]

If it lurches forwards with the lever pulled in, the clutch needs adjusting properly still.

Thank you. I’m not sure that’s the issue because once the clutch has ‘unstuck’ it is perfectly adjusted and only lurches when the bike is first started after sitting a few days, as if the clutch is not disengaging despite the lever being pulled. As I say, this normally only happens once then is completely fine despite there being no change in the way the clutch lever ‘feels’
