If there is no Lepton or Boson connected by USB then there is no warning or error presented to the user. If the app binary is launched directly from the terminal the following errors are printed:

Hey, I am having a similar issue. Running on Linux Mint Mate 64-bit on virtual box. My error is as follows:

Only use this in a safe environment. qt5ct: using qt5ct plugin uvc_find_device: No such device (-4) UVC initialized Surface set.

Was there a solution to this problem?

NOTE: VirtualBox is not friendly with the USB camera device, so used VMWare and worked like a charm, hope this helps others.
