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

[Sergei Shir]

Issue:

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.

Additional information:

(1) After I removed the "ExtSettings" folder from the "C:\Program Files (x86)\Notepad++\plugins", the Notepad++ closes WITHOUT any error.

Please add the following additional info:

• 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.

Thank you for providing exact debug info.

I've set up a test environment in a VM:

• OS: Windows 10 x64 v1803, version 10.0.17134, build 17134.1304
• Notepad++: v7.8.4 (32 bit), installed in %ProgramFiles(x86)%\Notepad++, running with Admin rights, same plugins like in your debug info
• ExtSettings plugin: v1.2.1, set up like in your screen shot

Notepad++ runs with session feature deactivated. All plugins except ExtSettings are running with default settings.

When I start Notepad++ and immediatly terminate it I can not reproduce your issue, no exception thrown during termination.

Please do some more testing. For example:

• Deactivate session feature ((menu) Settings -> Preferences -> Backup -> Remember current session for next launch) in order to start with an empty editor.
• Deactivate DSpellCheck plugin and all other plugins except ExtSettings.
• Deactivate cloud settings ((menu) Settings -> Preferences -> Cloud -> No cloud).
• Remove self-made contxt menu extensions.

Update:

Following the provided instructions, the issue was localized even more

There seems to be a conflict between these 2 extensions:
ExtSettings
DSpellCheck

When both of them are installed, Notepad++ shows this "Fast Fail Exception" error during exit.
When only 1 of these 2 extensions is installed, there is NO error.

The same update was posted at

Thank you
