Windows 10: Command promt opens and closes on startup

On startup command promt opens automatically and quickly closes in the flash of an eyeThis started happening randomly one day what should I do?

Command promts

I just recorded it happening and paused it when it happened and the command promt had nothing on it.

 

Settings and command promt not working

I recently made changes to my computer by accidentally selecting hidden in attributes of I think my Program files and after I did that my settings and command promt stopped working. All files are back to normal but my settings and command promt still wont
work. Command promt wont open with the hot keys and I cant search it in the search bar cause my search bar wont open(deleting cortana messed that up my search bar ..which is a different issue). As far as settings go I can pull up the settings but nothing shows
up only the options on the left of the menu. Here is an Example, I can click on settings and click on apps or security but nothing shows up just A white screen with the menu options on the left and settings freezes, In tast manager it says "application frame
host" not responding.

Currently I have ran the troubleshooter for windows apps which said it fixed some corrupt file but had no effect on settings or command promt.

The issues started when I made those file changes.

 

Two command line windows open and close quickly at startup

Hello,

Is there a way to tell which program is responsible for two command line windows that open one after the other and then close one after the other quickly at startup?

All I see is 2 black windows that open and close very fast but that's it

What can it be?

Thanks
