Dealing with Catalina

Hi

I upgraded by mistake :( Well, I fired up RStudio and ran my script I worked on yesterday (after having updated Xcode and the command line tools, and accepting the license agreement). Now, I get an error.

I use brms and it compiles and starts sampling but then during warmup I get this:

Chain 2: Iteration: 1 / 2000 [ 0%] (Warmup)
[1] “Error in sampler$call_sampler(args_list[[i]]) : "
[2] " c++ exception (unknown reason)”
error occurred during calling the sampler; sampling not done
