HTML input type=“file” in Google Chrome not showing popup window

This happened to me on Chrome v88.0, and I tried everything -- removing all the event handlers, making the simplest form possible, removing all other html and js from the page -- and still the file-selection dialog would not appear when clicking the "Choose File" button.

Then I shut down Chrome and re-opened it ... and it worked again.

Golden advice:

Have you tried turning it off and on again?

In my case the problem was as follows :

1. Whole document had a "on click handler"

2. Inside click hander, the code was canceling all propagation with

   return false;

Removing this return statement solved problem with input=file.
