Chances are high that you either have conflicting versions or mods. There isn't enough info to know for certain. The current version of this mod(1.3d in files) should be used with v1.0d of Strive(the current version out despite text to the contrary).
Also, I recommend checking the godot log file in the appdata(".../Strive/logs/godot.txt") for errors after the game closes, as that may clarify the problem. The last 8 lines will probably just be the game closing. If the log is empty(happens if game crashes), you might try the debug mod to enable the 2nd window which reports errors.
