Answer 1

As I can't yet comment questions, may I ask: are you using a virtual environment? Anyway, you could try with this command:

pip install pyqt5-tools~=5.15

Moreover, as @musicamante said, if you're using a Python version that's above 3.10, a downgrade to version 3.9 or older is recommended as pyqt tools ar still not compatible with >3.9 versions. However, as I've seen here, you can try installing an specific 5.15 release version, so please try:

pip install PyQt5==5.15.5
