Steps to repreduce:

1. Paste my code
2. Run the code
3. Stop the code
4. Run again
5. Stop again
6. Run again. This time the window will stack in the image i attached

When i removed the generated folder "token", then i saw the qr code again.

but the problem repeat himself when restart the browser.
