Could you help me please?

I have installed the latest version  9.6.5 of ol. Built the PDCDashboard. Fixed my code to import modules according file system of the package and proper calls, ex:

import OSM from '../../../node_modules/ol/source/OSM.js';
import TileLayer from '../../../node_modules/ol/layer/Tile.js';
import View from '../../../node_modules/ol/View.js';
import Overlay from '../../../node_modules/ol/Overlay.js';
import Polygon from '../../../node_modules/ol/geom/Polygon.js';
import Map from '../../../node_modules/ol/Map.js';

this.map = new Map({           
        layers: map_layer,
        target: olmap,
        view: view
    });


Everything looks like in examples of ol.

When I run the project, I can see that all modules imported successfully except Map.

I got error Cannot use import statement outside a module
enter image description here

If I understand right this is because of conflict between module systems in JavaScript: CommonJS and ES6 Modules.
There are several solutions in internet to solve it but the do not work for me.
1. Put "type": "module" setting in the nearest  package.json file. I can see that ol/package.json already has it.
2. Rename *.js to *.mjs. I cannot rename files int ol package, because they are prebuilt 
3. Use dynamic import. Again I cannot change the code of ol.
4. Maybe  the latest version of Node.js support together CommonJS and ES6 module systems. I use  Node.js v18.20.3. The latest version is 22.3.0. We cannot use it now, because we  will get conflict with node-sass. I tried and Oleg confirmed it.
5. Adding <script type="module">mport Map from '../../../node_modules/ol/Map.js';</script> does not help at all. And I cannot change Map.js

6. I tried to call ol from dist folder where it should be minimized like it was in earlier version. And failed. 
End etc. I checked all hypothesis I have found.

The main problem that openlayer package is prebuilt. Maybe it can be rebuild? How knows?

Maybe you have any idea how to solve it.
