Crashing upon file changes with the mega commit

[chungwong]

Problem

With the latest main which is up to 5f34822a66aacf13f3d7d221b93283d273f61ed6, I believe it was introduced by https://github.com/DioxusLabs/dioxus/commit/7ec3453ca36347a22c15634ac60eb6c4127fd57a

dx serve --example hello_world

Now make a change to examples/hello_world.rs

 fn app() -> Element {
+    "";
     rsx! {
         div { "Hello, world!" }
     }

It crashes at the second you save the change. Note: I made a few changes for logging and the line number is affected. Originally it panics at line 191

[packages/cli/src/serve/runner.rs:194:17] &rust_file = "/home/chung/repos/dioxus/examples/hello_world.rs"
thread 'main' panicked at packages/cli/src/serve/runner.rs:196:16:
called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Originally I thought there must be some error in the path but it is not the case, the path is valid.

❯ ls -l /home/chung/repos/dioxus/examples/hello_world.rs
-rw-r--r-- 1 chung chung 809 Oct 30 10:07 /home/chung/repos/dioxus/examples/hello_world.rs

Keeping this open until a fix is verified.

The above error No such file or directory was editing with Vim

I tested it again with gedit and the error is different

09:34:55 [dev] Full rebuild: /examples/hello_world.rs
09:35:03 [dev] Build failed: I/O Error: Text file busy (os error 26)
