Popping/clicking noise from road bike

Question

first posting here. I bought a second hand Madone 4.5 which makes this weird popping/clicking noise on a few gears, here’s a video to better describe. This happens on my stand or while riding. I noticed that the noise might be from the bottom pulley trying to grab on the spokes...
What I’ve done so far:

Clean and lube the chain, pulleys, front and rear derailleurs.
Changed shifter cables to Dura ace with polymer.
Indexed and adjusted shifting.

Bike components:
It’s a 10 speed Madone 4.5 with an 11 speed cassette.

Shifter: ST-5603 Shimano 105

Rear derailleur: RD-6700 Shimano Uletgra

Cassette: CS-R7000 Shimano 105

Front derailleur: Shimano 105 FD-5700

Chain: HG CN-6701 Shimano Ultegra

Can anyone help me solve this problem? Thanks in advance for your help.

You have a Shimano 105 5603 series 10 speed shifter paired with a Ultegra 6700 series 10 speed rear derailleur, as those are both 10 speed they will work together.
Those will not work with a R7000 series 11 speed cassette. Even if you thought you could just select 10 sprockets out of the  11 that does not work. Sprocket spacing is different between 10 and 11 speeds.
Also the HG CN-6701 chain is 10 speed specific and would not work properly on an 11 speed cassette.
Get a 10 speed cassette to make this setup work.
