Play and rule at the same time.

I created a random map and want to customize it. I want to play and, at the same time, notice any mistakes or shortcomings and fix them while playing a single game, so that I can play the next game properly. For example, there are bushes and trees that force you to go around in circles. Or, I want to remove unnecessary objects and replace them with ones I like. It's not possible to launch the editor separately from the game. I was thinking of downloading the editor as a separate program, but I can't find it anywhere. I can only find language packs, etc. Ideally, I need a separate program for the editor or a life hack, maybe someone knows.
