'QThread: Destroyed while thread is still running'

[Einridi]

Hi there,
I'm trying to convert a plugin written in python 2 (worked great) to python 3 so it works with the latest versions of calibre.

Ubuntu 22.04.1 updated
Calibre 6.7.1
Plugin 'Personnaliseur'
Python 3
Converting with py2to3
Fixing errors with PyCharm

However, when I try to launch calibre in Shell, nothing happens... except the following error message:
'QThread: Destroyed while thread is still running'
So I am unable to access calibre nor my library. I don't know how to open calibre to fix or remove this plugin.
I am self-taught and I admit that despite my extensive research on the web, I have not found a solution.

I think the easiest and provide you this plugin below. If someone could look at it... be indulgent, it's my first!

This is why I appeal to your wise advice.
Thank you in advance for your help.

Run calibre as

calibre --ignore-plugins

then you can remove the plugin using Preferences->Plugins

Thank you very much Kovid!
I was finally able to restart caliber and remove the recalcitrant plugin.
I will continue to search. If anyone has any advice or suggestions, I'm all ears.

@Einridi do you have access to Windows? If you do, you can install Calibre portable and use that to work on this plugin without causing any problem with your main Calibre install.

No, I haven't used windows for a long time, but I take note of this tip.

What does this have to do with Windows? You can do the same thing on Linux with the Linux version of Calibre.

Hello,
Despite multiple attempts, I still can't get my plugin to work in calibre (despite it being installed there and present in preferences).
Indeed, after starting calibre, the 'PersonnaLiseur' icon does not appear in the menu bar, nor in the contextual menu (right click).
Here is the associated debug report:

I add that I only modified the files in calibre_plugins.personnaliseur...
I guess you shouldn't touch the files from the calibre program itself ?

Does anyone have any suggestions to resolve this inconvenience ?
thank you in advance for your wise advice.
