Died from the wither effect, and none of my stuff dropped

Got killed by the wither, however when the death screen poped up, I noticed none of my stuff dropped, not even my netherite stuff...

So i went to look around to see if maybe the game lagged and when I respawned, and my stuff would appear, however after about 10 minutes of searching, I begain to worry if my stuff would be lost forever, then I begain to wonder if it my stuff never even dropped in the firstplace and this was a bug...

I died to the wither effect, not a explosion, so my stuff couldnt of been destroyed, there was no entitys that could of picked any of it up and wander off ether, I even dug down to see if it may have went thought the floor into some cave, however there was still no sighting of my stuff...

I was able to get footage of the incedent, however its only avalable as a youtube video...
