Whole Game won't work with new update

After the new update, my world won't work properly. It won't let me mine things and when I mine, the block will go away and come back a few minutes later. It also won't let me place things. I've been having trouble opening chests, doors, and levers. At one point I died from suffocation from the blocks not breaking and when I responded, my stuff all came back even though I don't have keep inventory on in my settings. Currently my game is unplayable because of these issues.
