Double this. Got a Trial license to evaluate if this software is worth it but the examples stop after 3 seconds tops with the above mentioned exception:
Create DepthProvider: AstraProPerseeDepthProvider
NUITRACK: LicenseNotAcquired exception (ExceptionType: 6)
The license.json file is present. All examples are affected by this problem.
When running “nuitrack_device_api_sample” this shows up
 20030530035 (Astra), License: None
I can run “nuitrack” to check the sensor is assigned the Trial license and it is marked as “3 minutes”. With other words although the license has been activated and is valid the samples/runtime fails to find it.
