Or it sounds like the computation probably is crashing the Sage instance

No, it seems to go beyond that. Even when I evaluate a cell containing
the number 1 or a string (so, no variable), there is no output. And it
can not be the reason that there is an undefined variable: There is no
output *and* no error. Nothing. Even if in a subsequent cell I use a
clearly non-existing variable, there is no NameError.
Then it seems like the Sage instance crashed, and so is not responding,
doesn't it? That has been my experience when I've seen these
symptoms---the backend Sage instance crashed and stopped responding to
the server's requests.
The worksheet indicates that it is busy working (by alternating / and
\ appearing in the page title), but it still accepts input.
That is your web browser doing those things. The backend Sage instance
doing the computations isn't affecting those functions.
