Orange crashes when browsing for file

[ferlocar]

Describe the bug

When I try to search for a file using the File widget by clicking on the folder option, Orange crashes (i.e., suddenly closes).

To Reproduce

1. Open Orange
2. Add a File widget.
3. Click on the folder icon.
4. Orange crashes.

Orange version: Orange - 3.24

Expected behavior Be able to search and load a file (e.g., a csv file) without Orange suddenly closing.

Screenshots I tried running Orange from the command line, this is the output message that I get in the command line after Orange crashes:

ERROR:orangecanvas.help.provider:An error occurred while fetching help inventory 'PyQt5.QtCore.QUrl('https://docs.orange.biolab.si/3/visual-programming/')'
Segmentation fault: 11

[Process completed]

Operating system: macOS Catalina 10.15.3

Additional context This is pretty much the same issue described in here: https://github.com/biolab/orange3/issues/4146

Are you using the official .dmg packages or did you install Orange in some other way? If so, how did you do it?

[ferlocar]

I'm using the official .dmg packages.

By the way, the problem started after I upgraded from version 3.23 to version 3.24.

@ferlocar, could you try executing /Applications/Orange3.app/Contents/MacOS/pip install pyqt5~=5.9.0 in the terminal and then restarting Orange? Here I am assuming that you copied Orange to Applications.

Also, what is the language on your system? Does your username contain and non-latin characters? What does pwd in a freshly open terminal show you?

[ferlocar]

We tried what you mentioned. This is the output:

The language of the system is English, and the username does not contain any non-latin characters. The pwd command shows the following: /Users/tuanhaoly

Just to clarify, this is an issue that a student of mine is having in his laptop. I'm teaching a data mining course using Orange, and that's why I posted this issue in his behalf. I will provide him the link to this issue so that you and him can troubleshoot the error together. We really appreciate your help on this.

@ferlocar, thank you. I asked you to execute /Applications/Orange3.app/Contents/MacOS/pip install pyqt5~=5.9.0 (with the full path, starting from /Applications). That command would replace a library from within the Orange app that was installed from dmg. Then you could try running Orange again.

We can't reproduce this, so we're closing the issue for now. If other users encounter something similar, we'll reopen.
