Package project : Unknown cook failure

[Nikuichi]

Hello all,

I’m running into the apparently infamous ‘unknown cook failure’ while trying to package my project.
I tried looking up the same error and found other posts but the tips given there were not working for me.

Here are the logs.
ExploProto_2.log (528.5 KB)

I am using Unreal 5.4.3

Any help would be greatly appreciated.
Thanks in advance.
