Just put a simple code block for test:

var http = require('http');
const { MongoClient } = require('mongodb');
      
var server = http.createServer(function(req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end("hello world!\n");
});
server.listen(3000);

package.json

....
"mongodb": "^6.12.0"

And package already installed in folder node_modules

But got error:

SyntaxError: Unexpected token '??='

Just removed the line const { MongoClient } = require('mongodb'); then it got to work without any errors.
If added back the line, then got the error.

So i guess there should be something wrong with mongodb, or mongodb package, but I could not find any other meaningful error message.

Could you please help take a look? Thanks a lot.
