UE4.25 cannot set the custom map as the default map, the solution

Problem: The map and mode in the project settings cannot be set as the level map created by myself, and can only switch between several default maps in the system.

Solution: Move the level map file created by yourself to the folder named in English (Chinese is not acceptable, it will not be recognized.)

It's very strange. When I was using version 4.24 before, I didn't have this kind of problem. I can only strengthen the habit of naming files in English.
