After Dell Update, XPS 15 (9560) freezes at Dell logo on start-up

Hello! Four days ago, I used the "Dell Update" application to update everything in my system. Many updates occurred (as I had not done it in a few months). Since then, my Dell XPS 9560 does NOT properly start up.

Specifically, if I close my laptop lid and re-open it, it will get stuck on the black screen (with the Dell logo) and it will NOT proceed. The circle with the moving dots (below the logo) will NOT appear. I have to reboot to fix this issue (manually holding down the physical button). It boots up the second time. This happens over and over.

I've already put in a Dell Support request and ran the F12 Diagnostics - the results of these tests are below:

After I showed Dell Support these outputs (from the Diagnostics), they said: "We received your request for the issue reported and have identified this to be a Software related issue."

This seemed obvious to me because this only started happening immediately after I ran the "Dell Update." 

Does anyone have any idea how I can fix this? Thank you!
