ValueError: Procedure called with not enough arguments

• OS: [e.g. Win 11]
• Python [e.g. 3.6.2 X32]
• PyQt5 [e.g. 5.15.2]
• PyCharm 2022.2.4

When I try the domos in example folders, all of them are not aviliable for me, it occurs the same error as below:

Traceback (most recent call last):

没遇到过这个问题诶，或许你可以建个虚拟环境试试看🤔

[ConyKitty]

Python 3.9的环境运行没问题，3.6就不行😂

可能和 Python 是 32 位的有关系，试下把 qframelesswindow/windows/window_effect.py 的第 26 和 27 行改为

self.user32 = WinDLL("user32")
self.dwmapi = WinDLL("dwmapi")

完美解决，谢谢！
