Have you made any attempt to introduce the crate slowly?
I have a 9 week old puppy. Day one - fed her all meals in crate, sat next to the crate/in same room playing with her, chucking toys in it, bits of kibble etc. That night she slept in it with a zip cover over, white noise playing, my worn dressing gown in there and me sleeping nearby. She woke in middle of the night and I took her to toilet with no lights on/no interaction and put her back. She cried a bit but I was sat outside crate hushing her.
During the following days I popped her in the crate every time she nodded off, carried on feeding in it, then gradually started closing the door and putting cover down for short periods in the day with music on (half hour after meals and toileting is a good time)
After a week she was sleeping through and now goes to the crate when she is tired in the day, and half hour after every meal when she sleeps 45-90 min.
Putting a pup straight in for an hour isn't going to work, needs to be done slowly but if it doesn't work, as others have suggested get a puppy pen to keep him safe - and don't leave him straight away, just potter about so he can see you and build it up. A Kong stuffed with food is a good distraction, soak the kibble and mush it up.
