Rebuilds fail on Windows in fullstack projects

[Hamcha]

Problem

dx serve fails to rebuild the project on Windows specifically when the change is not hot-reloadable. Hot-reload works just fine.
On my linux setup, none of this happens and everything works just fine.

Every time a new build is triggered, whether by the watcher or manually by pressing R key, a step will fail like this:

I have compiled the smallest amount of code that triggers this (mostly a stripped down template): https://github.com/Hamcha/repro-test

Steps To Reproduce

Steps to reproduce the behavior:

• Create a full-stack project
• Start dx serve
• Make any non hot-reloadable change or just press the R key

Expected behavior

Just like on Linux, a rebuild should work.

Environment:

• Dioxus version: v0.6.0-alpha.5
• Rust version: rustc 1.83.0 (90b35a623 2024-11-26)
• OS info: Windows 10 22H2
• App platform: fullstack

Questionnaire

I'm interested in fixing this myself but don't know where to start

This should be fixed in #3239. Can you test the Git version of the CLI?

cargo install --git https://github.com/DioxusLabs/dioxus dioxus-cli

Yup it works! Thank you very much!
