The aforementioned workaround fixed this for me as well.
@wenjiec_shen When are you guys planning to release the next version? It's been three months since you posted the workaround. For new customers--such as myself--this bug makes it seem that the SRWorks SDK is broken altogether (the example programs don't show any camera input at all).
@Jad Any update on when we might expect the SRWorks update to be available? I just purchased a Vive Cosmos specifically for SRWorks development, and am rather disappointed to not be able to use it given this SteamVR blocker.
