After upgrading from Fedora 35 to Fedora 36, I got this problem:
$ rails s

If you know the solution to this problem, I would be very grateful. Please answer me here or on stackoverflow (there is a more detailed description). Thank you.
NB. I don’t know what to do. Roll back to the old Fedora or migrate to openSUSE… I’m really in shock.
