How To Fix: File not found. Check the file name and try again on Windown 10

You have opened a file in an application like Microsoft Word, Excel, or even notepad, and when you save this file you get the following error message:
“File not found. Check the file name and try again.”

This is likely to be blocked by your Windows Defender Security Center.
It has a “Controlled Folder Access” option.
For more about these options, I refer you to the blog post from Microsoft.
