This application failed to start because no Qt platform plugin could beinitialized. Reinstalling the application may fix this problem. Available platform plugins are: direct2d, minimal, offscreen, windows.

在里面和外面搜了很多，最后在视频网站的评论区中找到了方法。

import os  
import PySide2  
dirname = os.path.dirname(PySide2.__file__)  
plugin_path = os.path.join(dirname, 'plugins', 'platforms')  
os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = plugin_path

把这段代码添加上去就可以了
