Old OZ imports not working -- ReentrancyGuardUpgradeable

Hi - I'm trying to "import @openzeppelin/contracts-upgradeable/security/ReentrancyGuardUpgradeable.sol" but the file is not found. The npm install does not include this directory path or file. Am I missing a different way to import? Here is the smart contract.

Thank you.

Here it is

github.com

OpenZeppelin/openzeppelin-contracts-upgradeable/blob/master/contracts/utils/ReentrancyGuardUpgradeable.sol

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.20;
import {Initializable} from "../proxy/utils/Initializable.sol";

/**
 * @dev Contract module that helps prevent reentrant calls to a function.
 *
 * Inheriting from `ReentrancyGuard` will make the {nonReentrant} modifier
 * available, which can be applied to functions to make sure there are no nested
 * (reentrant) calls to them.
 *
 * Note that because there is a single `nonReentrant` guard, functions marked as
 * `nonReentrant` may not call one another. This can be worked around by making
 * those functions `private`, and then adding `external` `nonReentrant` entry
 * points to them.
 *
 * TIP: If you would like to learn more about reentrancy and alternative ways
 * to protect against it, check out our blog post
