I have also experienced this; here is my full findings
Steps to reproduce:
On a Bedrock Realm, build a storage wall of double chests: 3 columns of doubles, 3 blocks high, in one row (x 28-33, y 73-75, z 26).
Confirm that all chests render correctly and that items can be moved in and out.
Enter a Nether portal and return to the Overworld. The portal is about 32 blocks from the chests.
Look at the storage wall and try to open the chests.
Observed result:
Some double chests are missing one half, which is invisible while its outline stays. The targeting box is a single-block size.
Chests, both the visible and invisible halves, open but won’t let you remove items.
Expected result: Chests render and work normally after changing dimensions.
Workaround: Leaving the Realm and rejoining restores everything. It breaks again after the next Nether trip, so the contents are intact and this is a client-side sync problem.
Additional notes:
Replacing the double chests with barrels removes the problem, which points to the paired-chest block entity.
Chests on both sides of a chunk border (x=31/32) are affected, so this isn’t only the known chunk-border case.
It looks related to the earlier MCPE-106030 / MCPE-109916 (half-invisible double chests).
TLDR; this seems like a client side chunk loading issue. None of the contents are missing and it only seems to be happening with double-chests; barrels are unaffected.
