Positron crash during R kernel start with ark issue on old Mac

[aleahy-work]

This seems related to posit-dev/positron#3812, which was marked as completed on February 12. When I start an R session on my MacOS 11.7 system (which should be supported according to https://positron.posit.co/download.html ) it fails with:

R 4.5.1 failed to start up (exit code -1)

The kernel exited before a connection could be established
