Hello @alan-kilborn, @Coises and All,
Yesterday, I was pretty sure the bug had been fixed. Unfortunately, today, perhaps because I needed to re-start my laptop for other reasons, the bug is still here
Of course, I re-ran the @alan-kilborn’s solution but without success
I tried to delete then re-assign the Ctrl + Shift + 0 shortcut to the Previous style of Find Mark style command within N++ => Not better
I turned my laptop off and then back on but no chance, either
I also visit the two sites, below, to get some tools to deternine which process could own the Ctrl + Shift + 0 shortcut => No result
https://www.nirsoft.net/utils/hot_keys_list.html
https://github.com/ITachiLab/hotkey-detective
Note that once Hotkeydetective.exe has been launched with administator rights, it is said to press the stolen key in order that the software shows you a path to the guilty process. However, hitting the Ctrl + Shift + 0 shortcut does not show any line, personally !
Finally, I had the idea of simply changing the Ctrl * Shift + 0 shortcut to Ctrl * Shift + 6. And… bingo, this change worked nicely !
Thus, doing the same thing for the Ctrl + 0 shortcut seems a possible solution to this problem !

P.S. :
After using this work-around, I tried to assign the Ctrl + Shift + 0 shortcut to a command without shortcut, like the View > Summary... command. But it does not show the Summarize dialog :-((
In contrast, the shortcut Ctrl + 0, which is no longer used, displays the control character 0, as I did not check the Settings > Preferences... > Editing2 > Prevent control character (C0 code) typing into document option. Thus no need of the Control Panel feature !
