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

[spoodyman]

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
