- const file = await import(fullPath);
+ const file = await import(pathToFileURL(fullPath).href);  // import parameter is file:///C:/<FILEPATH>

   const fullPath = path.join(directoryPath, filePath);
   - const file = await import(fullPath);
   + const file = await import(`file://${fullPath}`);  // import parameter is file://C:\<FILEPATH>

   OR

   + import path from 'node:path';
   // ...
   const fullPath = path.join(directoryPath, filePath);
   - const file = await import(fullPath);
   + const file = await import(`file://${path.resolve(directoryPath, file)}`);  // import parameter is file://C:\<FILEPATH>
