I understand how difficult this is.
As to the question of whether he can simply not pay, the answer is no, he can't do nothing and expect there to be no consequences. There is a court order in place, which is legally binding. He could, however, probably apply to amend the order if he has gone from having a £200k salary to being unemployed. If the reality is that he has no income, then the court will assess a change of circumstances if he makes this application. This application would require full financial disclosure again, and he would have to demonstrate that he cannot afford to pay before a court would amend the order.
If he does not make this application and simply doesn't pay, then he's in arrears and you can apply to enforce the arrears. This would be a D50k application for general enforcement as you don;' know how best to go about getting what you are owed given that he is presumably being cagey about his employment and assets.
The outcome of an enforcement application could be that the maintenance is reinstated, or that you are awarded a charge over any property he has, for example.
Be aware that enforcement isn't swift though, and there are still delays in processing cases through court following the backlash of the Covid-19 shutdown.
But there are options - and hopefully I have explained what they are.
All references to court forms are form the www.gov.uk website.
Do remember that I can only give you my opinion.
Another lawyer may have a different opinion. If there was a black-and-white answer to every legal problem there would be no need for anything to ever proceed to court!
