Hi, can you provide some replication code

I tried to write a demo, but failed to reproduce, the problem is in the company project, I can only remove the scoped to solve

Hi, can you provide some replication code

I'm having the same problem, it's a sporadic one. The same code is built multiple times, and errors may occur. I suspect that there is asynchronous processing logic between multiple loaders. After compiling, it is found that the source parameters of the two compilations are inconsistent in the loader(source) step.

source diffs:

// no windicss
<template>...</template>
<script lang="ts" setup>...</script>
<style lang="scss" scoped>...</style>

// has windicss
<template>...</template>
<script lang="ts" setup>...</script>
<style  lang="scss" scoped>\n...\n</style>

vue generate scopeId

 const id = hash(isProduction
        ? shortFilePath + '\n' + source.replace(/\r\n/g, '\n')
        : shortFilePath);

so vue-loader generate scopeId is different.

I tried fix it in #129 . Please help to see if it is possible .

Very sorry for the delay, the fix has been pushed.
