Unable to connect to Internet while in Safe Mode with Networking

Thank you for the information - await screenshot of your dev. mgr in Safe Mode showing your network card.
Unfortunately you're correct, those troubleshooters don't run in Safe Mode. So much for advice on the internet...

Please see this 'solution':
Network In Safe Mode Not Working

I've attached a copy of the services I have running in Safe Mode in 2 formats. You can check the key ones and compare.

I should have asked - are you connected by ethernet or WiFi?

then went back to the way it’s been for the past week. Is there any way to roll back to a previous version without losing any files I downloaded?

You can normally uninstall cumulative updates, so you could look to see which the last update was that you received - including any possibly relevant drivers- and try uninstalling that.
