"Error: spawn wmic ENOENT" when trying to GET /display

[boardwarp]

Hello, I just installed System-Bridge today and found that most of the GET endpoints are working great, but /display doesn't seem to work. A few seconds after sending the request, the S-B settings window crashes although several of its processes remain running, and no response is received in Postman. The errors below also appear in the log. Since I've never had this working before I'm not sure if it's a support issue or a possible bug so I thought I'd ask here first.

This kind of error does occur when trying to access the display brightness. Try running the app as administrator (this should be the case anyway, but worth the check). It could also be an error with the library being used. Does your display have a brightness to be set?

I'd been trying with the same results from both a desktop PC and a laptop, the laptop definitely has an adjustable brightness. Was pretty sure I'd been trying as admin too, but trying again just now from the laptop, as admin, gave the same error and crash sequence.
