Blocks path although server proxy applies

Describe the bug

I am building a client for my file server and need to serve the same index.html for almost every path. Precisely, I am using server.proxy to map each path matching "/D:*" to "/" via vite.config.ts like this:

import {defineConfig} from "vite";

export default defineConfig({
    // ... other options
    server: {
        proxy: {
            "/D:*": "/"
        }
    }
});

But if I try to access http://localhost:5173/D:/Images, it restricts access because D:/Images (folder) exists. This is not unique to this folder; any path that exists is getting blocked, while paths that are not found just resolve to "/". This should not happen since the URL is getting remapped.
