Rstan not working after RStudio update

Hi everyone,

Today I updated RStudio to its latest version (2023.03.1+446) on my two Macbook Pro laptops (one with an Intel chip running macOS Monterey and the other with an Apple m1 chip running macOS Ventura), and now I have been getting this error every time I try to use brms:

Error in unserialize(socklist[[n]]) : error reading from connection

Any idea what is going on here and how to solve it? I never had this problem before running the same analysis with brms.

I really appreciate your help on this.
Thanks so much
