Please update the project for the new 4.25 stable unreal engine version.

For now, you could use the 4.21.2 version of Unreal Engine, it works with that one. To add another Unreal Engine version:

1. In the Epic Games Launcher, click on Unreal Engine in the left navbar
2. Click on Library on the top navbar
3. At Engine Versions, click on the +
4. Now you can add another UE installation with another version
