Rasp Pi 4 & z-wave install help?

Hey all. I too am new to this and am having an issue with z-wave. Home assistant loaded onto raspberry pi 4 with no issues at all, however, I was unable to get my Zooz S2 z-wave plus stick to run or install properly. Below is the error I get. Any help would be appreciated.

A couple of questions:

  1. I loaded the HA image directly to RPI4 without any other OS. Is this an issue? Should I load an OS (Linux) onto the RPI4 first?
  2. Is Config file, similar to root? I am not an IT guy or anything but I am wondering if yaml acts similar to code?

“2020-05-04 18:35:14 ERROR (MainThread) [homeassistant.bootstrap] Failed to parse configuration.yaml: in “/config/configuration.yaml”, line 21, column 18: Unable to read file /config/zwave_device_config.yaml… Activating safe mode”

Again, thank you for any and all assistance.
