I quite often have the problem that RStudio stops working in a strange way.

The symptoms are as follows.

I enter a command in the console, e.g. 1+1 and press the enter key, but nothing happens. There is no red sign that indicates that the session is busy, no + at the beginning of the line that indicates that R believes the command is not yet completed. The console just keeps acting as a normal text editor, I can write stuff, press enter and it shows a new line etc., without a + or a > in front of it.

RStudio itself will be able to save files, navigate folders, etc., but nothing that requires it to communicate with the R instance (e.g. checking version).

Sometimes, after a ridiculously long time (e.g., 10 minutes), R will parse all the commands as if I just entered them.

I have the feeling that this is connected to when RStudio tries to autofill suggestions following a $ in a large tibble, but this is a wild guess.

This problem occurs with various versions of RStudio and R, e.g. 2024.04 and R 4.3.2. I am on windows.

I appreciate any suggestions how to proceed in addressing this issue.
