Problem with Hybrid Ultrasound Simulation

Hi Alejandro,
I tested your code with a few modifications and everything worked well. Now I have the segmentations and the Ultrasound Sweep. Your work has been really helpful.
However, when I try to run the Hybrid Simulation I have the following problem:

Couldn’t create OpenCL image (-59)
Ultrasound Simulation: Sweep simulation failed! Couldn’t create OpenCL image
Couldn’t create OpenCL image (-59)

I get the same issue when I generate the two glsplines from my own tracking sequence and I try to run the Hybrid Simulation, so it seems more likely to be related to my machine/configuration than to incorrect inputs. I am currently running everything on CPU only (no dedicated GPU). Can you confirm that this could be the reason of my problem?
I send to you the link of the workspace: https://drive.google.com/drive/folders/109zRZUufa2gH9leZc6aeId0cZevh4PbF?usp=drive_link

Best,
Chiara
