RStudio frequent fatal error and session aborting

Hello, I've been running into issues with RStudio encountering a fatal error and the session aborting not infrequently since yesterday. To my knowledge, nothing has changed about the computer or RStudio or the code. I've had some luck running the code line by line, but this is not always fool-proof and not a viable way forward.

I'm running the latest version, R version 4.4.1 (2024-06-14) -- "Race for Your Life"
Operating system: macOS Sonoma 14.5.

**i've repalced my user name with 'username' in the text above for privacy .

  • I'm running the same code that previously did not cause any issues (~ a week ago).
  • I've tried uninstalling and reinstalling both R and RStudio, but the problem persists.
  • The only packages I'm loading are tidyverse, styler, and readxl.
  • My files are all stored on a work server, and I also often encounter 'Error Saving File', which may come up if the server times out. However, even after I reconnect to the server, the issue persists and I have to quit and restart RStudio. (not sure if this is related or not, but might explain some of the errors above)
  • in /Users/username/.local/share/rstudio/log/rsession-username.log, I'm also seeing two .log files (rsession-username.log, and rsession-username.1.log

I'm at my wits end and am not sure where to go from here, so any help/suggestions are appreciated.

Thank you in advance
