Pressing "Advanced" does nothing.

Problem description

When trying to add a new theme using the Advanced menu, no Advanced prompt is shown and hence the user is unable to install custom themes. Clicking the button just causes the window to close.

Checklist

Please replace the space inside the brackets with an x if the following items apply:

• I've restarted Anki to see if it helps
• I've verified that I use the latest version of the add-on by redownloading it from AnkiWeb
• I've tried to disable other add-ons to see if there are any interactions present
• My issue disappears when I hold shift while starting Anki. (Clicking "CONFIG" in Addons -> Recolor brings up the advanced menu)
• I've checked if anyone else reported this problem before by looking through the issue reports. I also checked to see if there is a section about known issues in the add-on description, documentation, or README.

What Anki version are you using?

*Please open Anki, go to Help → About (windows) or Anki → About Anki (mac) to find the version. Edit the value between the backticks below

Thank you for the bug report!

This is probably a Qt bug, but I think it can be worked around by removing the below line of code. I'll try to push out a fix soon.

self.setAttribute(Qt.WidgetAttribute.WA_DeleteOnClose)

Meanwhile, you can access the 'advanced config' by editing the add-on config after temporarily disabling the add-on. (Or by editing add-on config in safe mode)
