If the clutch was installed by a garage you should take it back.
An internet search comes up with topics on judder from a new clutch. As an example which turned out to be a faulty new flywheel https://www.bimmerfo...g-issue-t98338/
Whilst not normal, it might bed in after a few miles. Causes of judder I have experienced include
- wear on the flywheel face so it was not smooth and had wear ridges, Sanding these out cured it but it then wore quickly needing doing again and really needed a new flywheel.
- worn spigot bearing/bush in the middle of the flywheel
- worn clutch plate
- oil on the clutch face
You could also bleed the clutch since if there is air in the hydraulics it would not help smooth pedal operation. A smear of grease should have been applied to the splines on the input shaft to allow smooth movement of the clutch plate.

Could be an engine mounting, the one low down at the back can cause judder. If it did not judder before the clutch was replaced then the mounting might have split when replacing it. As a quick check with the bonnet lifted, get somebody to rev the engine up and down and see if the engine rotates a bit - it should not. You would need to look under the car to check how bad it is.
