I checked for recent open and closed bugs, and none seem to match this particular one.

Describe the bug

After updating to Glances 4.2.1 with Homebrew, I get this mess of an error on start up.

If I run with glances --disable-plugin network, it starts up successfully.

Traceback (most recent call last):

To Reproduce
Steps to reproduce the behavior:

1. Start Glances on macOS
2. See error

Expected behavior
Glances start successfully without error.

Environement (please complete the following information)

• macOS 15.1.1
• glances 4.2.1

Glances version:        4.2.1
Glances API version:    4
PsUtil version:         6.1.0
Log file:               /Users/sam/.local/share/glances/glances.log

• installed with Homebrew
• glances --issue reports no errors

Additional context

I have considered whether this could be a configuration problem, but after checking these directories:

• ~/.config/glances/
• ~/Library/Application Support/glances/
• /usr/local/etc/glances/
• /usr/share/docs/glances/

I can't find any files in these places.

for x in ~/.config/glances/  "~/Library/Application Support/glances/" /usr/local/etc/glances/ /usr/share/docs/glances/; do echo $x ; ls $x; done
/Users/sam/.config/glances/
ls: /Users/sam/.config/glances/: No such file or directory
~/Library/Application Support/glances/
ls: Support/glances/: No such file or directory
ls: ~/Library/Application: No such file or directory
/usr/local/etc/glances/
ls: /usr/local/etc/glances/: No such file or directory
/usr/share/docs/glances/
ls: /usr/share/docs/glances/: No such file or directory

Here's the log output:
