Unfortunately, you will have to perform a new install. This appears to be a serious bug many are encountering with the new version of Windows 10.
I am going to recommend you downgrade to Windows 10 1703.
Yes, not the best news you want to hear. These feature updates are not thoroughly engineered and are rushed mostly to meet deadlines.They have become highly unnecessary in some instances. My opinion, focus on the apps and less on having the latest version of Windows. If your apps are working fine and you are getting your work done, minimize your need to jump on the latest release.
Now, get ready to go back to your previous version. I recommend Windows 10 1703 because its the most stable and efficient release to date.
Step 1: Go to another working computer with Internet access, download Windows 10 1703 from the following link:
