I ran across this nonsense today. Same error with features.dll. Program would start up and then close. 

The tool hub is completely useless. So don't even bother with that.

Uninstalling the program and deleting the folders from all the locations where intuit stores files did not work either.

What worked in my case was this. I downloaded the latest version of .Net from here. I installed .Net 4.8.1 and restarted. 

This time when I restarted the program. It actually started up and let me in. 

So for those of you with this issue. Try updating .Net on your system.
