Welcome to the forum!
As you are probably new to EB and its mechanics I'll suggest to read the FAQ and the Frequent Encountered Issues.

Use add_population CITYNAME -4000 to minimize the population

Use process_cq CITYNAME to build fast bulidings which support bonuses to civil order (if the money is missing use add_money 40000)

If you want to get around the RTW doplomacy you can use this minimod for EB.

If the problem is not solved after doing these steps please post here again.
