@jtsternberg 
Thanks for using Local!
I read through your linked threads just to make sure I’m up to speed. I’m not aware of any recent Local-specific issues or threads on this issue; from my understanding, all of these threads boiled down to machine-specific issues with the shell config (it seems reordering of $PATH variables was the most reliable fix - WP CLI errors, "Failed loading ... opcache.so" "xdebug.so" and "Warning: PHP Startup: Unable to load dynamic library ... imagick.so" code unsigned - #31 by afragen - this post was helpful!).
Have you looked into your shell config or the order of your $PATH variables? Also, what machine/OS and version of Local are you on?
