Hello and sorry for the late reply due to Eastern vacation.
What platform are you compiling to?
Can you please post or send me (support_AT_paradoxnotion.com), the log file of the game crashing?
This page of the Unity manual shows where the log file can be found [LINK]
For windows standalone for example, it can be found here: C:UsersusernameAppDataLocalLowCompanyNameProductNameoutput_log.txt.
