[Bug]: Error: File system access error

### Problem description

Website on Deno Deploy will occasionally fail to read files. The files are in a `/static/...` path, they are read through `Deno.readFile` API which the docs say Deno Deploy support: https://docs.deno.com/deploy/api/runtime-fs/#deno.readfile

Whenever I try to load the files, they load fine. But the error logs says that this is not the case all the time.

The error stack look like this when using `Deno.readFile`:

```
Error: File system access error (ddf77bfe-35b8-4e1a-9448-97a8b13ea488): open '/src/static/...image.png'\n at async Object.open (ext:deno_fs/30_fs.js:633:15)\n at async https://deno.land/x/fresh@1.7.3/src/server/context.ts:636:22\n at async handle (file:///src/routes/_middleware.ts...
```

Sometimes it is slightly different if using the `Deno.readTextFile` method:

```
Error: File system access error (98375883-8959-41ce-aa79-c32bc7665cb1): readfile '....someFile.md'\n at async Object.readTextFile (ext:deno_fs/30_fs.js:878:18)\n
```

### Steps to reproduce

It cannot be reproduced, it seems to be an occasional error. I can only assume that this is an error with Deno Deploy.

### Expected behavior

There should not be readfile errors

### Environment

- Deno Deploy

### Possible solution

_No response_

### Additional context
