The working one does sh -c ''/home/user/softwares/tor-browser/Browser/start-tor-browser' -detach || ( & '$(dirname '$*')'/Browser/start-tor-browser -detach)' dummy %k, whereas the old apt-pulled app has torbrowser-launcher %u.

While right clicking on the non-working 'Tor Browser' app and the working one, I notice a difference in commands.

But still that error when clicking on the apps. Which went well, as far as terminal is outputing.

Before downloading a new instance from torproject website, I tried repairing with sudo apt remove tor torbrowser-launcher -y without the -purge to conserve my bookmarks hopefully, then reinstalled it with sudo apt install tor torbrowser-launcher -y.

So I guess the two former apps were pulled from the apt repository (because installed via the 'Discover' KDE GUI).

I now have 'two' Tor, because the third app I'm able to launch is downloaded from torproject website, then I extracted their folder somewhere, opened the terminal here, and did $.

The two remaining ones lead to that tiny error window, while the third one does launch Tor browser, from which I'm able to post this thread. I also have a third app, called 'Tor Browser' as well.

When I go to the app menu, sub-menu 'Internet', I get the remaining apps 'Tor Browser Launcher Settings' and 'Tor Browser'.

Now the taskbar shortcut won't launch, only open a tiny window showing 'Download Error: 404'.

Today, because the browser was lagging and freezing/skipping frames while streaming videos, I gave it a shot and updated, it warned me it'll close my running instance and reinstall in the background. It's been ages that Tor browser has that update pop up.
