Unable to add files for review using P4 plugin

I've recently set up my mac for code reviewing using p4v for file syncing/ changelists and ccollab for the review platform. Versions are:

MacOS - 10.15.7

Perforce - P4V/MACOSX1015X86_64/2020.1/1966006

ccollab client - 13_1_13100

Via the coollabgui app, I have the SCM verified and connected with no errors. I am unable to add pending changelists for review, but I can add submitted changelists. What's more is I'm able to submit files for review by manually uploading them through the web client. The big headache comes when I attempt to use the smartbear custom tool that installation builds into P4V. Attempting to right-click and add any changelist results in the following error:

No SCM Configuration could be determined

Cannot run program "p4" (in directory "/Applications/ccollab_client/ccollabgui.app"): error=2, No such file or director

I have reviewed the following other topics and found no solutions:

Any ideas? It's looking like this could be a potential bug.
