Theme
Expected behavior
Be able to launch CLI's theme dev.
Actual behavior
Upgraded to CLI 3.81.0 and now I'm greeted with a JSON error - was working fine on 3.80.7.
Already tried uninstalling and reinstalling via homebrew.
I think this further solidifies the CLI team desperately needs to roll out stable and beta branches.
