Upgrade Unreal Project 5.2 To 5.4 - Bug Packaging unknown error

Hello, I’ve been trying to upgrade my current project from version 5.2 to 5.4 for a while now, but since the upgrade I can’t package the game at all, and I keep getting these errors.

I’ve been trying for a long time to find the cause and solve them, but so far I’ve come up empty on what to do about it.

Does anyone have any idea what they might mean or what might be causing them? (Knowing that in 5.2 and 5.3 I had no problem compiling and packaging the project, I assume that something changed in 5.4 or went wrong with the upgrade).

Thanks in advance for your help.
