The wiring in the image with the wiring in is not complete. There are no wires in the L1 or L2 holes.
Also, the neutral wires are connected to the switch, but the dimmer has no neutral connection, so the neutrals will have to go into a separate connector.

Apart from the switch with the wiring not being complete/correct, if you have already tried the dimmer and connected what appear to be N cables as well as L cables across the dimmer, you may well have fried it!

Where is it now?
Do you have a pic of the original switch before you re wired it? It would have been a like for like swap
One option is those browns are the wires for just 1 switch (not the neutrals) and the 3 core coiled up in the back box is for the other switch. 2 way switched elsewhere

The N Loop terminal of the old switch has no function apart from holding the neutrals together.
As mentioned earlier, they could be in a choc block terminal for all the difference it makes.
wiring the neutral across the new dimmer will have fried it. I bet it’s rather black now and smells of burning??
Without knowing what was in L1 or L2 of the old switch, we can’t advise further.
But it would have been a simple swap over, just by following the same terminal markings.

The terminal marked loop will need a connector block because the dimmer has no connector for it after that it is a wire for wire swap

Have you read any of the replies? Didn't you say that that configuration didn't work? So no dont duplicate it.
As well as the neutrals not being wired into the dimmer, the left hand switch can't possibly be doing anything with it wired like that
