Windows 10: Turning on Ransomware Protection in Windows Security prevents File Explorer from copying...

I just reinstalled W10 v1903 on a clean hard drive and set up Ransomware Protection in Windows Security. I added folders to protect. I cleared explorer.exe as Allowed through these folders. I then attempted to copy a file from one location to another, and I get the message "Could not find the item / This is no longer located in ..." I get the option to Try Again, but the only way this works is if I turn off Ransomware Protection. I have installed other apps (such as Adobe and Office) and have no troubles saving new files. How do I get File Explorer to let me copy files from one place to another?

Say goodbye to ransomware with Windows 10 Fall Creators Update

Yes, ransomware will be a thing of the past with Windows 10 Fall Creators Update thanks to something called "Controlled Folder Access" in Windows Defender.

These are protections for your files against ransomware at the kernel and Windows Defender level. Rest easy, your files are safe.

About damn time Microsoft!

 

Malware and ransomware protection

First things first:

1.) If you’re using Windows Defender, then the first thing you need to do is turn on Windows Defender’s new built-in
Ransomware Protection – known as “Controlled Folder Access” (it’s disabled by default):

Stopping ransomware where it counts: Protecting your data with Controlled folder access - Microsoft Security

Turn on the protected folders feature in Windows 10

2.) The next thing you should do is prepare for the worst by creating a backup of all of your personal files on a removable hard drive, flash drive, or recordable disk – and then disconnect the drive. If you have
additional PCs, you can transfer your backups to those PCs. Once everything is backed up to an external device, you’re prepared to make a complete recovery in the event that your files
are rendered inaccessible by malware or encrypted by ransomware. No one can destroy all of your personal files, or hold them hostage, if you just have your own copies of those files. It's really just that simple. So it should
be reassuring to know that there is a surefire way to prevent the loss of import data and documents
– because the threat landscape is evolving so rapidly that there’s really never any surefire way to prevent a malware or ransomware attack. "Back up your files" has always been the
prime directive for any sound security strategy:

3.) Then, as time permits, you can go ahead and educate yourself to your heart’s content about all of the proper steps and strategies for avoiding malware and ransomware – keeping in mind, of course, that things are moving
so fast that a good fraction of what you read will already be outdated –
and remembering always these ancient words of wisdom: "The most profound knowledge of how to avoid pitfalls is of little use to a man trapped in a storm sewer".
