All widgets show no appearance or layout properties.

[Dennis802]

Hi! I've been using Pygubu Designer for a while now. I hadn't used it in 3 months, so starting it today I wanted to make a new UI project but it turns out not a single widget shows its properties anymore. I can create toplevels, frames, labelframes, buttons and labels but the properties screen to the right remains empty.

Steps to reproduce the behavior:

1. Open any project
2. Click on a widget
3. Check properties panel to the right
4. An empty void ;)

Expected behavior
Showing the properties of said widget where possible.

I have tried reinstalling PyGubu and Designer, and Python itself as well, but to no avail.

Your Environment (please complete the following information):

• Windows 11
• Python 3.11
• Pygubu 0.31
• Designer version 0.36

Keep up the beautiful work! PyGubu is awesome stuff.
