Hi Dave
My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.
Have you installed any new hardware or software since this problem started?
The following 'tw-bac' is said to be associated with Task Scheduler. i would look there to see if you have any random programs that might be using it to generate any of those temp files.
The recommendation is, they can be safely ignored.
You can configure Windows 10 to delete them automatically.
Click Start > Settings > System > Storage > Configure storage sense or run it now
Check the box, Delete temporary files my apps aren't using.
