I'm running into the same issue.
On a Nobara 40 system.

It's definitely installed on my system as well.

$ dnf list installed | grep webkit2gtk
webkit2gtk4.0.i686                                    2.46.1-2.fc40                                    @updates                  
webkit2gtk4.1.x86_64                                  2.46.1-1.fc40                                    @updates

I fixed the issue.

Run sudo dnf install webkit2gtk4.0-devel
It immediately worked for me afterwards.
