PandasGUI getting an error with PyQt 5

PandasGUI breaks off during an execution. It looks like it's related to PyQT: it can't execute it.

Do you have any suggestions why that could have happened?
Thx in advance!

### Code
```
import pandas as pd
from pandasgui import show
df = pd.DataFrame({'a':[1,2,3], 'b':[4,5,6], 'c':[7,8,9]})
show(df)
```

### Error Traceback
```
