Research direction
Reproduce cam -c 1 -C on the Raspberry Pi 4 with the IMX219 sensor and kernel 5.10.1-v7l+, then inspect the reported V4L2 and dmesg errors. Trace the failing format setup through the camera and kernel components; done means identifying a compatible fix or confirming the kernel/libcamera compatibility issue.

Description
I followed the instructions to install libcamera on rpi. (I use rpi 4 model B and my sensor is imx219)
The rpi-update command leads to kernel 5.10.1-v7l+
Then, when running the command:
cam -c 1 -C
I get the error:
ERROR V4L2 v4l2_videodevice.cpp:931 /dev/video13[out]: Unable to set format: Invalid argument
The dmesg says:
[87627.802495] bcm2835_mmal_vchiq: error -1 queuing message
[87627.808096] bcm2835-isp bcm2835-isp: populate_qdata_fmt: Failed vchiq_mmal_port_set_format on port, ret -1
