CLI 2 not connecting to desktop app; unable to determine parent process

Hello all - I'm trying to setup 1Password v8 with the CLI v2 coupled with biometric authentication (on Mac OS 12.2.1). I'm stuck at getting the CLI to talk to the desktop app:

➜ settings op vault ls
[ERROR] 2022/04/08 10:38:07 connecting to desktop app: determining parent proces of 1326: operation not permitted

• I've checked the Preferences -> Developer -> Biometric unlock for 1Password CLI
• I've verified my op executable is in /usr/local/bin
• I've verified the permissions are set to 600 on /Users/{username}/Library/Group Containers/2BUA8C4S2C.com.1password/Library/Application Support/1Password/Data/settings

Suggestions? Thanks in advance.

1Password Version: 8.7.0- build 80700041, beta
Extension Version: Not Provided
OS Version: macOS 12.2.1
