    …
    app.setLabel("img", "Selected Image: " + ("Yes" if did_select_img else "No") + ". Using grabbed image.")  # setting a label on the outer "normal" window here
    app.destroySubWindow("imgGrabSelect")  # error occurs here

What steps are needed to reproduce the bug

---

The code I provided should already show the error.
If you want, you can run my program (just one File):
https://gist.github.com/8a3c3df95e039f4ae15e44f5b857dd25

You need a chromium selenium webdriver, set the path to the driver using the variable DRIVER_PATH at the top of the file.
Start the program,
Click on "Grab Image", enter a search term (e.g. Dogs), wait until downloaded, click on one of the available images in the subwindow that opens and look in the log.
