@Ivan-Bútora ,
Everything there looks good so far, so nothing there. That makes me think it’s the Mark of the Web.
Exit Notepad++.
Open up Windows Explorer, navigate to C:\Program Files\Notepad++ . Right click on notepad++.exe, do Properties, and make sure the bottom of the General tab doesn’t have the “unblock” checkbox:

if it does, checkmark it, and choose Apply / OK
Then go to c:\Program Files\Notepad++\Plugins\Config, and do the same right-click Properties > General check on nppPluginList.dll. (Since Notepad++ runs, but the Plugins Admin doesn’t show up, this is most likely. I just started with the exe to be methodical.)
Then also check c:\Program Files\Notepad++\updater\gup.exe , just to make sure it will update properly in the future.
If that works: then, in the future, if you manually ran the installer exe , you might want to check for the “unblock” on the installer before you do – I think if you unblock that, it will then not block the exe/dll that it installs. Similarly when downloading the zipfiles, unblock the zipfile, and everything you extract will inherit being unblocked.
