The second error ("VIDIOC_STREAMON returned -1") is a symptom of the first: since the topology hasn't been configured properly, trying to start streaming over it won't work either.
I've updated the Wiki page you cite to give example commands that work for me on a 6.9 kernel. Please see the page again, and hopefully the new version will help.
(Unfortunately, the rkisp1 driver seems to change frequently, so the example commands are rather fragile. In general, deducing the correct commands for your particular driver version might require some interpretation of the "media-ctl -p" output.)
perhaps this explains why snapshot has stopped working on alarm then? 6.9 kernel....
