The first thing to do is always to download and flash the most recent image available, and to let it perform all its updates when you first boot it. Don't change or reconfigure anything at all and "libcamera-hello" should just work. Can you confirm whether you've done exactly that?

The kinds of errors you have are often typical of long or faulty ribbon cables, power supplies that don't work as well as they claim (very common), or other hardware problems. Where you have spares so that you can rule things out by testing the spares, that's helpful.

If after that you're still having problems, you might do better to file an issue on the libcamera-apps Github.

Yes, I did it. Now Im testing with a legacy image. I ve tested with a fresh os and different cables, as well different raspberrys

using legacy image fixed my issue.
