Thank you for your help, this is good to know. I didn't think it is bash that
could be doing that.

The two commands did not fix the problem, though.
After running the first one, @ still cant be typed, and after running the
second one typing # does not comment the line anymore, but a # is not typed
either. As I perceive currently nothing happens when attempting to type @ or #.

Also, when we figure out the exact problems (in case there is more than what
you have discovered already), would it be possible to integrate the solution
into Konsole?
Windows Terminal passes these inputs to bash by default in a way that doesnt
confuse it, and it would be very helpful if Konsole too worked out of the box
that way.
Not sure how is it with other layouts, but among Hungarian keyboards its common
to have the right Alt as an AltGr key.
