Anything in the logs or a references that might be useful?

Please upgrade and see if your issues are fixed

Hi @timmo001 , I'm afraid I don't really see much improvement.

First I removed data folder to start fresh. (c:\Users\Mitja\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\Local\timmo001)

Still some SQL errors on startup and the GUI is still blank. I clicked on "show settings" on 14:53:14 timestamp. Everything before that was simply me running python command and watching the output (no input from my side).

I also have this problem. Additionally, I get an error of:

The code execution cannot proceed because Qt6WebEngineCore.dIl was not found. Reinstalling the program may fix this problem.

pyside6 is installed without problem, confirmed by running python -m pip install --upgrade pyside6

System Bridge 3.4.1 is installed.

I can open the GUI log, grab the URL, and open it in a browser though.

FYI, same occurs with 3.4.4

[timmo001]

I had an issue with a laptop that had pyside6 installed but not fully. I ended up running:

python -m pip install --force --upgrade PySide6

which fixed the issue of PySide7 not being found

I figured out my problem.

1. Don't use Python from the Windows Store - it is a bad idea and not recommended by the Python devs.
2. Install Python directly from the Python website, and ensure to check the checkbox which says "Add Python [VER] to PATH" - this is critical for Python to work correctly from the CLI and for third-party dependent libraries to load, like Qt6WebEngineCore.dIl. @timmo001 - I would recommend stressing this in your documentation (Windows Store does not setup PATH and does not give you an option to).

I also use Python from Windows Store. Solved missing Qt6WebEngineCore.dll by adding new OS environment variable

QTWEBENGINEPROCESS_PATH=%USERPROFILE%\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\PySide6\

But the GUI from within the app is still not shown. It shows the main window, it blinks once and then this is the logged error. I can still access the GUI from the browser but would be nice to have this working as well.

This is Windows 10 headless server and I tried from RDP session as well as from TeamViewer (thinking that display driver is to blame).

I've done all of my testing via Remote Desktop. As I mentioned in my previous posting, do not use Python from Windows Store - it's part of what caused my problems.

Here's some more reading on the weirdness of fake pathing that the Store does to its packages:
