VirtualBox on Windows 10 super slow all of the sudden

I'm using VirtualBoox with Windows 10 using Linux Ubuntu within VirtualBox

I've been using my virtualbox for over 2 years and have had no or minor issues that were always resolvable.

I hadn't used my virtualbox in over a month and booted it up and its taking 15+ minutes to boot and each click and type is taking a minutes to respond.

I attached my log. Is there anything in the log that pops out to you that I can fix?

A few things I have done but still slow

--Upgraded to latest version after i noticed it was slow
--Assumed because my SSD was almost full, I removed a bunch of applications

Your log has this line.

HMR3Init: Attempting fall back to NEM: VT-x is not available

This is a common problem. See this post.
