Why is my blockchain.com not receiving bitcoin? I created a wallet on blockchain.com, copied the address from the '' bictoin request '', sent it to the person, and that person sent me a bitcoin after a few hours.
After a few hours my laptop restarted. When I logged in again, the Bitcoin address was different.
Bitcoin was sent to that address, but my wallet no longer recognizes the address it generated.

Can I recover the amount of bitcoin? What can I do?
Your bitcoins are not lost.

What you observed is completely normal behavior which one would experience across most wallets. The wallet generates a new address once it detects that you have received coins on the previous address. This is done to minimize address-reuse which improves the privacy of the sender and the receiver. 

This has nothing to do with your laptop restarting.
