Baby won’t crawl

Anyone else baby is 10 months but won’t crawl?😭 he won’t crawl at all my baby will stand up but only if he is grabbing something to help him balance himself he can sometimes stand up and thrown himself to the things he wants to grab but other than that he won’t crawl I put him in tummy time and he hates it😭 I think he can’t crawl because he is a little bit heavy he is about 30 pounds and very tall. He also moves a lot but only if he is in walker he walks. Help
