Vite module runner has been closed

[DanOfir]

Describe the bug

After upgrading to version 6, a hot reload in the development environment leads to a server crash without recovery.

Reproduction

vite.new

Steps to reproduce

1. running the sever locally using: pnpm remix vite:dev
2. go to any path for example /health -> should return OK
3. trigger save in vite.config.ts -> should trigger server restart ([vite] server restarted)
4. go to any path again /health , now it will return 500 with an error "Vite module runner has been closed"

revert to Vite 5.4.11 to fix the issue.
