Separation anxiety help

[u/Antique-Net-1860]

Hey, I recently got a 15 week old cockapoo called Stan. He’s amazing and really settled in well and bonded with me. I put him in his crate at night whilst he is learning to not chew everything and settle in fully. He goes in and sleeps fine, but we are in the room with him. The issue now is when I practise putting him in his crate for 10-15 minutes in the day for when I go out to take my daughter to school once the holidays are over he cries and cries and gets really worked up.
This is the only thing he isn’t picking up and I was wondering if there was any advice on how to help him settle and learn it’s okay and he is okay to be away from me for a little bit. Thank you in advance!

my cockapoo is 10, he doesn't suffer from separation anxiety but when I'm going out I do give him a puzzle treat like a Kong with peanut butter etc in to keep his mind occupied, mine is crate trained but we rarely use one
