Hello and welcome to justanswer, My name is ***** ***** i will be assisting you today,
I'm sorry about the issue, Please try pressing F8 repeatedly on startup (before windows 10 logo appears), and see if there is an option to refresh your PC. Choose option to troubleshoot > reset this PC > keep my files
you may need to reinstall any missing programs. Your documents and files will be safe.
Let me know the results
