Describe the issue:

I get the following error when running code.

Error refreshing variables: RPC timed out after 5 seconds: {"jsonrpc":"2.0","method":"list"} Error (-32603)

The interface then becomes sluggish.

This only happens in 2025.01.0-152.

Steps to reproduce the issue:

Expected or desired behavior:

No error.

Were there any error messages in the UI, Output panel, or Developer Tools console?

Developer Tools console

workbench.desktop.main.js:616229 Error refreshing variables: RPC timed out after 5 seconds: {"jsonrpc":"2.0","method":"list"}  Error (-32603)
c @ workbench.desktop.main.js:616229

I'm also seeing the same error on 2025.01.0-152, running R 4.4.1 on Ubuntu derivative (Pop!OS). I thought it was something up with the quarto interpreter, as it seems mostly to affect sending commands from quarto to the console, but yeah, everything feels sluggish.
