Edge. Reproducible issue so weird that its hard to believe it happens.

When you highlight the word(I typed it myself) in the text editor, there is no problem. Just in the other members post.

I have no idea, but on my machine Windows already sent a report(Report ID) to Microsoft(see your reliability history)

Code:

Description
The program MicrosoftEdgeCP.exe version 11.0.14393.51 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.
 Process ID: c78
 Start Time: 01d1fd088e3bae5c
 Termination Time: 11
 Application Path: C:\Windows\SystemApps\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\MicrosoftEdgeCP.exe
 Report Id: ef69885a-68fc-11e6-a086-c03fd53709f0
 Faulting package full name: Microsoft.MicrosoftEdge_38.14393.0.0_neutral__8wekyb3d8bbwe
 Faulting package-relative application ID: MicrosoftEdge

Until a fix is made, you might want to try, opening an extra tab(right click current tab at top, and select duplicate) when copy & pasting. So if the tab freezes, you can just close it, but not all of Edge, as each tab has it's own process.

The issue has just been confirmed as reproducible by MS.

Yay :)

Now they probably know what causes it, it'll get fixed, hopefully soon.
