I am encountering the exact same problem, however I have a temporary fix that works for me.
Just boot up your computer and bring up the boot menu (hold F8 during bootup) and then select "Safe Mode With Networking" from the menu. This will load Windows in safe mode with minimal drivers
. It doesn't look pretty, but you'll be able to get online to upload those big files. Once you're done, just reboot as normal.
Hope that helps.
