This appears to be similar/related to #10057, however is relates to a failure to generate a complete manifest, not what the #10057 issue results in which is a build failure.
I have created a reproduction repo with a write up in the README there.
The generated manifest is stomped on during compilation. This looks like some kind of race condition where two
different processes build but do not coordinate to produce a unified final manifest (speculation) -??
Warning Output
$ yarn build
"rendering chunks (1)...The emitted file "manifest.json" overwrites a previously emitted file of the same name."
Error State
The manifest contains only one of the build assets:
[X] Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
[X] Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to vuejs/core instead.
Describe the bug
This appears to be similar/related to #10057, however is relates to a failure to generate a complete manifest, not what the #10057 issue results in which is a build failure.

Below is that README description of the issue.
Issue Sample
Context
When Vite uses a worker (which emits a seperate chunk in the production build) and is configured to export a build manifest, eg:

Warning Output

Error State
The manifest contains only one of the build assets:
