Blocks unplaceable in certain areas

My friends and I have been playing on a realm for quite some time. We've been having a lot of fun, but then this glitch came out of nowhere. It started by the first house in the video, but then quickly started spreading to others. It also affects all players on the realm, and not just me. It only happens in some areas of the realm, and it gets really annoying. Blocks can be broken just fine, but once they are, the glitch makes it so it's impossible to place them back. I hope you can stop this glitch so my friends and I can start playing normally again.
