Assertion crash when launching packaged game

Hi!

I’m trying to package my game for Win64 using UE 4.21, I was successful at the beginning of the project but now I get a crash when I start the .exe file directly in the “WindowsNoEditor” folder generated when packaging the project :

Didn’t tried much, considering it takes a long time to package the project for every test!
Got an idea of what’s the problem ? Thanks!

Edit:

I found the crash log, which I added to this post.[Log file][2] [Log entire folder zipped][3]

At the end of the log I found :
“Couldn’t find file for package /Script/DiscordRpc requested by async loading code. NameToLoad: /Script/DiscordRpc”
I just started using discord, is there anything special I have to do to include the discord plugin when I publish ?
