You are getting the error because you have a wrong version of qt on your machine. I mean it seems anaconda installs the wrong version of QT by default. First, you need to install essential packages (enter link description here) and then do the following steps:

2. conda remove pyside2, qt, pyqt5 if you have installed them with conda
3. conda install -c conda-forge pyside2
