RStudio session aborts immediately after typing

Hi everyone,

I’m having a strange issue with RStudio on Linux. As soon as I start RStudio and try to type anything in the R script new or old one (even a single letter), I get:

“R Session Aborted
R encountered a fatal error.
The session was terminated.”

My setup:

  • OS: Linux (x86_64) Ubuntu 20.04.6
  • When I checking in bash - R --version
    I got:
  • R: R version 4.4.2 (2024-10-31) -- "Pile of Leaves"
    Platform: x86_64-pc-linux-gnu

when i open Rstudio i have a warning massege - "youre using 2024.04.0+735 - Rstudio
and that a newer version is available: 2025.09.2+418.

I would prefer not to update R itself right now, because I’m worried about breaking my existing package setup, and some packages are hard to reinstall on this system.
I also saw a few posts when people get the same issue of R sessions aborts after installing a new version, so it's confusing.

Questions:

  1. Could this crash be related to an incompatibility between my R version (4.4.2) and this RStudio version (2024.04.0+735)?
  2. Are there known issues or bug reports about RStudio 2024.04.0+735 with R 4.4.x on Linux?
  3. What logs or diagnostics should I provide to help debug this? (e.g. ~/.local/share/rstudio/log/, rstudio-diagnostics, etc.)
  4. Is there a way to fix this without downgrading R or completely reinstalling all R packages?

Any suggestions or pointers would be very helpful.
Thank you!
