how to get out of session$attach()

[venpopov]

I ran this code:

library(callr)
sess <- r_session$new()
sess$attach()

which opened an interactive console within the external session. I tested a bit, and typed q() to exist it, which I guess was a mistake, as now my console is completely non-responsive:

> sess$attach()
RS 1018860 > ls()
character(0)
RS 1018860 > a = 1
RS 1018860 > ls()
[1] "a"
RS 1018860 > 
RS 1018860 > q
function (save = "default", status = 0, runLast = TRUE) 
.Internal(quit(save, status, runLast))
<bytecode: 0x55b1affd2158>
<environment: namespace:base>
RS 1018860 > q()
fsdf
1
exit
q

Two questions:

• How do you get out of a console from a session you attached (in general)?
• In this case, after having typed q() and my console is unresponsive, what can I do to get back to my original session and console? I am currently running a few background jobs in this Rstudio session, so if I restart the session I will loose the jobs (they've been running for 40ish hours...)

Press CTRL+C, or the stop button in RStudio.

Neither of these work. There is no red button like usual and ctrl+c has no effect unfortunately

If it's relevant, this is in rstudioserver via a browser

Try pressing ESC while the console is active. How do you usually interrupt a command?

ESC worked, thank you! I usually interrupt with ctrl+c, and didn't occur to me to try esc when that failed.
