The world is in my own realm run through bedrock. If there is a chest on top of a chest the lower chest will not open. If a double chest is the lower and a single is the upper only the spot below the single will not open. The other half of the double chest will open and give access. I have add-ons but they never had any issues till now. The only add-ons I have are only from the marketplace. Below is clip showing me doing the bug.
