Error: Failed to start camera

Raspberry Pi4 + Arducam ToF Camera.

When I try to run example "preview_depth" I get error "Failed to start camera" with error code ArducamSystemError (-2). What does it mean? Something wrong with camera? Does it relate with last commits in this project (1 month ago it worked well)?

I'm also getting this error. I think it affects 0.1.5 and 0.1.6 (maybe 0.1.4, I haven't tested it). Downgrading to 0.1.3 does work. You'll need to make sure you use code written for 0.1.3 as the SDK's API has been changing in the newer versions.
