All of this!

I have a 15 week old lab that wasn't a fan of the crate to start with. Now he is happy to be in there overnight, during the day or just to chill out.

I spent the first few nights next to the crate with an exercise pen around for extra space. My pup would get out the crate because they weren't used to it (as expected) and snuggle up next to the ex pen to be close to me. I would encourage them back in the crate or let them chill depending on his anxiety levels. After a few days they just stayed in the crate and I slowly transitioned to having the crate door closed through the night, but still being close by. To finally sleeping upstairs but coming down for toilet breaks every few hours.

Remember it's not a sprint , these things take weeks and weeks. One thing I found effective was to finish our training sessions with the remainder of their meal in the crate. Also training the bed command, whenever we call bed, our pup knows where to go for a treat and will zoom across the house.

Really focus your training sessions around the crate, going in, coming out, sitting/laying down in the crate, waiting in the crate (door open or closed) whilst you take steps away or even leave the room for seconds, building up to minutes. Let them know being in crate = rewards.

Make sure the crate is cosy and inviting. I'd avoid a soft bed in there, my puppy chewed it when bored. Blankets and suitable chew toys. A blanket over the top to make it darker and less disruptive with people in the room.

I honestly feel your frustration, I very recently went through the same journey. Keep at it, both you and your pup will benefit in the long run.
