Plot pane shows just black screen

Question

Working on RStudio Server 2023.06.1 Build 524. Somehow I messed up the graphics device configs. E.g. plot(1) creates just a black new tab in the plot pane. Weirdly enough, the zoom window will show the plot. Other devices, e.g. png(1);plot(1);dev.off() also work fine.

I tried the usual stuff to no avail, e.g.

> graphics.off()
> dev.new()
NULL
> dev.list()
RStudioGD       png 
        2         3 

I also closed the project, completely logged out of RStudio Server, manually killed all my rstudio-server processes - same. Found no relevant *.Rdata files and rsession.conf and rserver.conf have no entries.

I also cleared browser cache, tried a different browser - same.

Any clues?!

The error occurred after I accidentally ran a large script with many plots and impatiently hit Esc a few times to stop it.
