To answer your question "why this happens".

As you can see that the code in validateURLScheme() checks if parsed scheme is one of above four $allowed_schemes. Since windows directory convention is different than linux, the function always returns false due to local windows files do not validates the condition.

To avoid this convention issue we add !file_exists($filename) condition. !file_exists() will satisfy if condition only when file is not found. Since file is found it will return true from validateURLScheme(). Which solves our problem.

As Kalvin mentioned in comment Magento v2.3 is not supported in Windows OS as per official doc. So we had to make such changes in core files.

Hope it answers your question. Thanks

  • Yes definitely it will. when you update your Magento version, the core files are replaced with new ones. So you have to redo them. To get rid of this the suggested approach would be to use VM stack. Commented Jul 6, 2020 at 5:56

You cannot install Magento2.3.5 on Windows. It must be installed on Linux environment only. If you want to run Magento on Windows, use VM tools e.g. Vagrant , Virtual box, Docker. Many Magento features are supported under Linux only e.g. symlink inside pub/static css/js file
