I just updated RStudio to 2025.09.0 Build 387 on two machines, and suddenly I seem to have every R package known to mankind installed on both. On my laptop, most of them are in the system library rather than the user library; on my desktop, most are in the user library. The system library on my desktop has maybe 30 packages; on the laptop, there are now 12 starting with the letter "a"! The abind package is in the user library on the desktop and the system library on the laptop.
Prior to the update, the laptop had a rather small collection of packages overall. When I tried to update packages after updating RStudio on the laptop, the install.packages command in the console exceeded the maximum console line length of 4094 characters and the operation bombed.
This is very confusing. Is it happening to other people? Why is it happening?
I just updated to this version (2025.09.0 Build 387) as well and suddenly, I can't run a particular code in my project. See attached . Pleese, how do I reinstall the previous version?
I would start by resetting RStudio's state, just to see if that fixes it. If the problem persists, uninstall RStudio, repeat the instructions from the link to remove the state files (which are not deleted when RStudio is uninstalled), and look for the version you want here.
Can you please file a bug report at GitHub · Where software is built? Also, can you confirm what version of R you're using on each machine, and whether you have anything like a custom .Rprofile or .Renviron file that could be affecting RStudio's behavior here?
