Yes. But once I could kill it straight with C-x c without any
questions or something.

It happens during eww call, not immediately but during. I could do 3
times C-g and get the error and then after nothing, I could not kill
buffer, could not quit, nothing but xkill

Now, last 3 attempts I can interrupt and I get keyboard control, I can
see half page loaded. And I can kill buffer.

I was thinking maybe ivy, but I turned it off, it is not ivy.

So if I just interrupt it during loading, I have no keyboard control,
but if I continue interrupting with C-g then half page appears and I
get keyboard control.
