[Bug]: InternalFailure error

### What happened?

Sometimes when running aspect, I suddenly get `InternalFailure("Shutdown errors: [Timeout(5s)]"). When it happens, all `aspect` commands after will result in this error.

### Version

Development (host) and target OS/architectures:
Windows 11

Output of `bazel --version`:
8.5.1, but also happens on 9

Version of the Aspect rules, or other relevant rules from your
`WORKSPACE` or `MODULE.bazel` file:

Language(s) and/or frameworks involved:

### How to reproduce

```shell
Unknown
```

### Any other information?

Happens on Windows 11 cmd, powershell and in wsl.
This issue seems to disappear for some time when restarting.
It is not a regression, at least over the past few releases have tried some different ones.
I think it might be related to running multiple projects with bazel at the same time and using aspect for multiple at the same time.

Stack (happens for all `aspect` commands once it starts, even `aspect`, `aspect --help` and so on):
