Can't Package Project

I’ve been working on a project for school on UE4, whenever I try to Package the project it opens up the internet instead I have no idea why it does that, it’s really frustrating because whenever I try to redo it the internet opens when I try to package it. Any tips?

Having the same issue…

Same issue for me - building to Lumin platform worked for half a day then suddenly just takes me to UE4 docs? Any ideas? Thank you.
