Some double chests become two single chests

I have also seen this issue. Two double chests have become single. I can see the hitbox for the other half but cannot open is as the server crashes with :

I have been to the Nether and back, but it has not resolved it. I've started server and client in various orders, still no good.
Seen in 1.16.100.4

Was half of the chest invisible? If so, that is a duplicate of MCPE-106030.
