The dependency service or group failed to start

Background - I'm a newbie trying to experiment with PDQ Inventory and Deploy on the free tier. My expectation is that I wish to be able to at least cruise around the UI to learn about it, then add more computers and try some simple software inventories and deployments on another family PC here at the house, but today I'm just trying to start with my personal laptop Win10 laptop, I'm the sole user and the Admin.

I installed Inventory and Deploy_19.0.40.0 today, but got error messages when I logged in (same as for Inventory or Deploy, so I'll only show one). What does it mean, how do I move past this? Is there some other service that needs to be running?
