Older dog acting out after puppy got a crate?

Hello! I got a 6 month old puppy about a month ago and the older dog who is almost 3 and pretty well behaved just started acting out. I was giving my puppy free roam of the house but it wasn’t going well, he was getting into too many things while I was gone and I came home to a destroyed house every day even after removing anything I believed he could get into. I got my puppy a crate and he has been okay so far. My older dog had extreme separation anxiety as a puppy and actually chewed through a metal crate when he was younger. Since the puppy got a crate the older dog has been going in it and today I got a call from my landlord that “the dog” was going crazy. I stopped down the block on my way home and heard the bark of the older dog (the puppy doesn’t bark very much to begin with). Is it possible the older dog is jealous that the puppy has a crate?
