OAK-D LR not working when link left and right cameras

I bought a camera oak-d lr, and tried the example from https://github.com/luxonis/depthai-python/blob/main/examples/StereoDepth/depth_preview_lr.py but for left and right cameras. Seems like it blocks and doesn't return queue names from queueNames = device.getQueueEvents(). In case I link left and center it works. Any ideas why that could happen? Or maybe some docs?
