Hello @837852427, thanks for reporting this issue! Can you please include your Python version?

Also, did you try uninstalling PyQt6 and installing PySide6==6.5.2 instead?

Below is my python version Python 3.10.9 (tags/v3.10.9:1dd9be6, Dec 6 2022, 20:01:21) [MSC v.1934 64 bit (AMD64)] on win32 And I just tried manim-slides==5.0.0 and PySide6==6.5.2 it worked! Though it doesnt have the next slide info window but it satisfies my request now.

I'm happy that fixed your problem! I'll keep this open because I have to investigate why PyQt6 stops working.
