RStudio 2024.12.1 Build 563 stalls when indexing into a large array -- R does not!

When indexing into a large array, RStudio 2024.12.1 Build 563 ("Kousa Dogwood" Release (27771613, 2025-02-02)) for windows stalls, potentially indefinitely using gigantic amounts of RAM on a Windows computer (see the example below). Performing the same operation in R (4.4.3) directly, works like a breeze. It also works in RStudio 2024.09.1 Build 394.

this legitimately takes some time

test=array(runif(1000^3),dim = c(1000,1000,1000))

this should be quick but stalls RStudio 2024.12.1
