I recently have samiliar issue, 13900k + 4090 seems to be a bad combination some how. But I kinda found a work around, goto th Intel website and download “Extreme Tuning Ulitily”, then set p-core and e-core down a little bit, and the crashes and blue screens never showed again. Just give it a try.
I see a lot of people reporting problems like this, all related to 4090+13900k. I m guessing the hardware development is too fast for the dev team to experiment every combination.
