Sounds very much like root damage. I've just been through the dreaded vine weevil attack which does exactly this but in your case it's more likely to be connected to the repot. Possibly the tree was not wired or secured in firmly enough and movement caused by wind or other causes has meant the tree cannot build new hair roots thus putting it into instant drought and killing it (I have just done this myself to a Chinese elm where I didn't give it due care). The check here is to push the trunk of the tree with your hand - if the pot moves the tree is secure - if the tree moves it not secured properly yet - if so, you need to secure it better (ask again if this is the case) and give it plenty of water and some root grow or other root tonic to help it recover. You may also have caused a similar problem by letting the roots dry out as you repotted it. Many people mist their tree roots during the repotting process especially on a warm day if the fine roots are exposed for more than a few minutes.

In the root photos they do look very dry. How long were they out of the bed before you got them into the pots? Did you cut back the foliage mass to give them a chance to recover? They had a big lot of foliage for a small looking root ball

Chinese Elms are tough though and with a bit more tlc they might rally round.

Couple of hours at most before I repotted it. I didn't cut anything back though
Hopefully it will pull it back

A couple of hours is quite a long time for roots to be exposed and dry like that. For future repots it would be better to have everything ready for the repot before you start so the roots are exposed for a few minutes rather than a few hours. If you find you are delayed, wrap the root ball in a damp cloth or spray with water or put in a bucket if water. Anything really to stop them drying out. The little hairs on the roots will shrivel very quickly in the air.

Thanks for the advice. Much appreciated
How much and how often should I water it now ?

You need to aim for moist soil - not too wet and not too dry. How often depends on the weather and the health of the tree. I would put it out of the sun, somewhere sheltered and check it daily. Water if the soil is dry below the top centimetre or so.
