bazel unable to build typescript locally on windows

Question

I have created a projectB to experiment ts build with bazel.

Here is my BUILD file

load("@aspect_rules_ts//ts:defs.bzl", "ts_project")

ts_project(
    name = "ts",
    srcs = ["say-hello.ts"],
)

• I have pass Windows 10 to dev mode as required (it fixed a first issue)
• I have installed MSYS2

But I am stuck with this error now and I don't understand how to dig it:

> bazel build //packages/projectB:ts --enable_runfiles=true --verbose_failures

I even tried to run the batch validator.bat, and I got this, but I'm not sure this is the actuel error... Maybe I'm invoking the command the wrong way:
