I have been developing a personal project and I am getting this error:

transact to Lottery.(receive) errored: VM error: revert.

Can someone help me?

contract Lottery { address payable[] public players; address public manager;

constructor() {
    manager = msg.sender;
}

receive() external payable {
    require(msg.value == 0.1 ether);
    players.push(payable(msg.sender));
}

function getBalance() public view returns(uint) {
    require(msg.sender == manager);
    return address(this).balance;
}

 function random() public view returns(uint) {
    return uint(keccak256(abi.encodePacked(block.difficulty, block.timestamp, players.length)));
}

}
