Unable to open html files into microsoft edge using VS code


This Content is from Stack Overflow. Question asked by suborno das

I am using vscode for working on my html skills along with microsoft edge browser to open the file. A while ago, just as usual, I wrote a code , saved the file and pressed F5. After that it appeared like this:
whenever i press f5, the toolbox on the top-right keeps popping but then it disappears.

I searched my way through it and I think it has something to do with launch.json(run>add configuration) as I code here is showing like this.

"version": "0.2.0",
"configurations": [


        "type": "",
        "request": "launch",
        "reAttach": true,
        "name": "Launch index.html",
        "file": "${workspaceFolder}/index.html"


Now i have no idea about json and i cant able to figure it out what is wrong with it.
