Fast Fail Exception - A fail fast exception occurred. Exception handlers will not be invoked and the process will be terminated immediately.

I opened the following ticket:
https://sourceforge.net/p/extsettings/tickets/1/

If the "ExtSettings v1.2.1" plugin is installed in the Notepad++, when you close the editor, it shows this popup:

*Fast Fail Exception
A fail fast exception occurred. Exception handlers will not be invoked and the process will be terminated immediately.

Please add the following additional info to your ticket:

• Windows version and bitness. For Windows 10 please include the exact version number, e.g. v1809, v1903, and so on.
• Notepad++ debug info. You can get it by clicking on (menu) ? -> Debug Info -> Copy debug info into clipboard
• A screenshot of your ExtSettings plugin dialog. This way I can see the settings you are using.

Please don't expect a quick fix. Currently I'm very busy in my job and can spend only limited time for my hobby projects.
