RStudio does not open on my Mac and it keeps crashing. I’ve tried uninstalling R and RStudio and install different versions of RStudio. I have also updated my Mac and tried re-installing. When it starts, I get a message that says “R has encountered a fatal error”.

I am running on macOS Sonoma 14.5.

If I open R outside of RStudio it works. A very interesting issue is that when I create a new user on my mac and try to open RStudio there, it works. I have attached an image of what it looks like when I try to open RStudio. Below is the error message that I copied.

I would appreciate any help, thank you!
