Randomly Unable to Open RStudio

Hi,

Would appreciate help in troubleshooting my RStudio install. It was working fine until one day when it just wouldn't open, with the problem report copied below. I've tried reinstalling both R and RStudio, and have deleted all R startup files. I also tried the command sudo chown $USER ~/.local/share . R runs fine when I try to open it independently of RStudio. Any ideas? I'm wondering if it has to do with the Copilot AI plugin I had recently installed...

Problem report below, thanks!

EDIT: fixed by running this code in terminal!

rm -rf ~/.local/share/rstudio
