IMX219 Auto Exposure & AWB not working

I'm using a BTT Manta M8P, BTT CB2 and a Raspberry Pi Cam v2 (IMX219).

It used to work just fine, but after a few updates AWB and AE are not working anymore. The rkaiq_3A throws an error:

The image stays at a fixed, very low exposure and is really dark. Exposure values won't get updated.

Start by reproducing the IMX219 issue on the BTT CB2 and inspect the rkaiq_3A log, especially the bad media topology and isp_3a_stats_poll errors. The issue is resolved when auto exposure and auto white balance update normally and the image is no longer fixed at a very low exposure.
