ERROR: You must use the PyQt5 bindings

I'm stuck! As far as I know nothing changed (except I did turn off my pc) from when everything was working until I became unable to open any VCP in Qt Designer.

The other strange behavior is that now when I invoke editvcp on the command line, I get a file chooser dialog with no option to create a new vcp.

The main error I got when running editvcp vcptemplate from the command line is the following:

2022-05-18 19:49:49,986 - EditVCP.Designer - INFO - Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

To try to diagnose the problem, I've placed print statements in the file, /home/dave/.local/lib/python3.9/site-packages/qtpy/__init__.py. I'm showing the state of the "API" variable. As can be seen, it stays set to "pyqt5" before the open file dialog but after I choose (any) vcp to open, you can see the variable change to pyqt6, then pyside2. I don't think it's suppose to do that.
dave@DavesLinuxMachine:~$ editvcp
(DL Diagnostics line 105 - API = pyqt5
(DL Diagnostics 2- API = pyqt5
(DL Diagnostics line 130 - API = pyqt5
(DL Diagnostics line 132- API = pyqt5
(DL Diagnostics line 156 - API = pyqt5
(DL Diagnostics line 205 - API = pyqt5
Note: at this point I'm presented with a file open dialog box instead of launching Qt Designer directly.
The following is the output in the terminal after I choose (any) vcp to edit:

Thanks for the suggestion, TurBoss but it didn't change anything. Here is the result:
dave@DavesLinuxMachine:~$ sudo apt-get install  python3-pyqt5
[sudo] password for dave: 
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
python3-pyqt5 is already the newest version (5.15.2+dfsg-3).
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
dave@DavesLinuxMachine:~$

Before your suggestion, I had actually uninstalled python3-pyqt5 and then reinstalled it. When it was uninstalled, Qt Designer opened normally but didn't contain any of the VCP widgets. Reinstalling python3-pyqt5 didn't change the errors I was getting.

I realize I may have improperly shut down my computer which may have caused the problem. Does this fact give you any other ideas?

Thanks!

I did the following but it didn't change the behaviour:
dave@DavesLinuxMachine:~/dev/qtpyvcp/pyqt5designer/Qt5.15.2-64bit/python3.9$ sudo ./install.sh
[sudo] password for dave:
renaming existing libpyqt5.so to libpyqt5.so.old
copying libpyqt5.so for python 3.9 to /usr/lib/x86_64-linux-gnu/qt5/plugins/designer
dave@DavesLinuxMachine:~/dev/qtpyvcp/pyqt5designer/Qt5.15.2-64bit/python3.9$

Note that my vcp runs fine when launched from linuxcnc. So I must have the pyqt5 libraries.


I've attached the
/home/dave/.local/lib/python3.9/site-packages/qtpy/__init__.py file which is where an exception is thrown and this causes the API var to change from pyqt5 to pyqt6 and then pyside2.

I realize it's a lot to dig into but I'd be curious as to why that exception is thrown.
