Fatal error running bayes_factor()

I want to compare two Bayesian models and always get a fatal error when running the function.

Every time I run the models, the following warning messages come:
Compiling Stan program...
sh: clang++ -mmacosx-version-min=10.13: command not found
The NEXT version of Stan will not be able to pre-process your Stan program.
Please open an issue at
https://github.com/stan-dev/stanc3/issues
if you can share or at least describe your Stan program. This will help ensure that Stan
continues to work on your Stan programs in the future. Thank you!
This message can be avoided by wrapping your function call inside suppressMessages().
Start sampling
Warning messages:
1: In system2(CXX, args = ARGS) : error in running command
2: In file.remove(c(unprocessed, processed)) :
cannot remove file '/var/folders/2s/_43kyxq500jc0kzljbg3r26c0000gn/T//RtmpbzKpTr/file3095bedc50e.stan', reason 'No such file or directory'

In addition, I get a fatal error when I want to run the function bayes_factor().

I am currently operating with MacOS BigSur 11.6.1., RStudio 1.4.1106.

Start by reproducing bayes_factor() on macOS Big Sur with RStudio 1.4.1106 and inspect the reported clang++ compilation failure. Done means the Stan program compiles and bayes_factor() completes without the fatal error.
