Hi, I am taking a course for data and programming skills where we use R and R Studio. I have downloaded R and R studio respectively as instructed. However, R studio does not start up, and I get the error " Cannot Connect to R". I can open R and also code on it, making me believe that R works. I have also deleted and downloaded both applications several times. Here is a text that R studio showed after a while on it.
My device is a Macbook Air M1 13inch.
I have also confirmed that my software is MacOS 26.3 Tahoe.
