SDK 5 ZED_Depth_Viewer not showing depthmaps

Software
1

I downloaded and installed the SDK 5. I can see the stereo pair images in the ZED_Explorer. I launch the ZED_Depth_Viewer but it doesn’t show any depth maps. At the same time in the terminal there are some errors:

I’m using ubuntu 24.04 in a Thinkpad P16s Gen3.

I’ve been running apps using opengl and cuda/pytorch successfully so I don’t think the problem comes from there.

I can’t attach the diagnostic file as I’m a new user. I can try to post instead in the next message.
