It’s really strange. It will work fine from a fresh opening/save, but it will crash if you click “Play” after changing a setting, (The jump height in the MyCharacter Blueprint for example).
If you save the setting before the inevitable crash on PIE, the setting will be saved and it will Play OK after the crash with the new settings. It’s simply after any change it’ll crash on PIE.
I don’t expect you to be able to replicate it in house without them, so there’s a link to the project files here:
