### Describe the Bug

I am experiencing an issue in Next.js when attempting to import dynamic routes using the dynamic function in turbo mode. This issue occurs when the --turbo suffix is set in package.json.

Steps to Reproduce:

Enable turbo mode by setting the --turbo flag in package.json.
Start the Next.js project.
Attempt to dynamically import routes using next/dynamic.


Current Behavior:
When the project runs with the --turbo flag, an error stating "Module not found" is encountered during the dynamic import of routes. This error does not occur when the --turbo flag is removed from package.json.

### Expected Behavior

The application should successfully import dynamic routes without any errors, even with turbo mode enabled.

### To Reproduce

Enable turbo mode by adding the --turbo flag in package.json.
Start the Next.js project.
Attempt to dynamically import routes using next/dynamic.


**Repository for Reproduction:**
The issue can be reproduced using the code in my public repository: https://github.com/cyb1999/next-turbopack-dynamic-issue

Code snippet:
// SidebarContent.tsx
```bash
'use client'
import React, { memo, useCallback, useMemo } from 'react'
import dynamic from 'next/dynamic'
import { SidebarMenuConfig } from './SidebarMenuConfig'
import { usePathname } from 'next/navigation'

interface DynamicSidebarComponentProps {
  componentPath: string
}

const DynamicSidebarComponent: React.FC<DynamicSidebarComponentProps> = memo(
  ({ componentPath }) => {
    const DynamicComponent = useMemo(() => {
      return dynamic(() => import(`${componentPath}`), {
        loading: () => <div>loading...</div>,
      })
    }, [componentPath])
    return <DynamicComponent />
  }
)
DynamicSidebarComponent.displayName = 'DynamicSidebarComponent'

const SidebarContent = () => {
  const pathname = usePathname()

  const relevantPathSegment = pathname.split('/')[1]

  const currentMenu = useMemo(() => {
    return SidebarMenuConfig.find((menu) => relevantPathSegment === menu.path)
  }, [relevantPathSegment])

  if (currentMenu) {
    return <DynamicSidebarComponent componentPath={currentMenu.componentPath} />
  }
  return null
}

export default SidebarContent
```

//SidebarMenuConfig.tsx
```bash
export const SidebarMenuConfig = [
  {
    path: 'chat',
    componentPath: './ChatSidebar',
  }
]
```
