Tab Key doesn't indent in VS Code

When programming in VS Code, I always use the Tab key for indenting. But, I was surprised that is stopped working all of a sudden. How do I fix this?

You have enabled the Tab Moves Focus -mode.

Press Ctrl+M to disable the mode. After that your Tab-key indents your code again.

Pressing Ctrl+M did not disable the mode for me, however the right side of the bar along the bottom of vs-code shows Tab Moves Focus as enabled, which you can click to disable.
