Clutch pedal stuck

Hello, I know the topic is there often already. With me it’s just that, I step the clutch, switch it, let the clutch come in, clutch moves in normally again, the pedal also comes up a bit again from the ground and stays hanged only then. Doesn’t always happen. Now that it’s colder but more often. I only have a few 1000km of the car and it was badly switched from the beginning, but wanted to blame the rejected circuit. Type: 9000CSE 2,0 LPT Model’93 from Italy. 275 tkm, clutch allegedly new. Greeting Niels
