Different OS version, but looks like essentially the same issue as #57912.

I'm guessing the issue is that OpenBLAS failed to properly detect CPU features, and enabled AVX512 even though it's not actually available. You can get an idea of what OSX thinks the processor's capabilities are via a command such as sysctl -A | grep -i avx .

Sometimes the "devel" port will work, since it contains fixes since the latest release. Thus, can you try installing the "openblas-devel" port and see if that works?

"devel" port, same issue
