Due to the differences between website and web application (opens in a new tab) projects, the system cannot import from one to another automatically.
For packages that contain physical files, you need to complete the standard import procedure, and then manually perform the following steps to ensure that your web application runs correctly:
The import places all physical files from the imported package into the ~/App_Data/CMSTemp/ImportExport/Files folder (or a different folder if your application has the CMSTemporaryFilesFolderPath web.config key set to a custom folder). Copy the content of the folder into the CMS folder of your web application project.

Include the files that did not exist in the project before the import:
Convert the project to the web application format:
Rebuild the solution.
If you are importing a package from another web application project, you do not need to convert the files (step 4), but it is still necessary to include the imported files in the project.

To add files or objects that require compilation, you need to perform the import on the original project and run the precompilation again.
