VS code icons disappeared

In VS Code, Go to extensions Ctrl + Shift + X .

Under installed extensions, select the vscode-icons extension. And Click on Set File Icon Theme, as shown in figure below, then press Enter

You need to set “workbench.iconTheme“: “material-icon-theme“.
Then reloading the window should fix it.

I had to install the extension again. I am on Mac, so I had to go to Preferences -> Extensions, and searched for Material Icon Theme, installed it and relaunched the IDE.

Based on my own experience, the theme was being deselected due to some reason (e.g installed a new theme, application update and etc) may also cause this issue, you can fix it by re-select the icon theme:

Open VS Code, go to File > Preferences > File icon theme > [Theme name] and choose your icon theme.
