很奇怪的现象，控制台没有报错。但是本地ctrl + s 保存后再次预览就成功了

import JSZip from 'jszip'

/**
 * Strip [Content_Types].xml Override entries that reference files not present
 * in the ZIP archive.  Some PPTX generators (e.g. certain web exporters) emit
 * phantom slideMaster entries that crash @vue-office/pptx with a silent error,
 * producing a blank render.

export async function sanitizePptx(buf: ArrayBuffer): Promise<ArrayBuffer> {
  const zip = await JSZip.loadAsync(buf)
  const ctFile = zip.file('[Content_Types].xml')
  if (!ctFile) return buf

  const ct = await ctFile.async('text')
  const fixed = ct.replace(/<Override[^>]*\/>/g, (match) => {
    const m = /PartName="([^"]+)"/.exec(match)
    if (!m) return match
    return zip.file(m[1]!.replace(/^\//, '')) ? match : ''
  })

  if (fixed === ct) return buf
  zip.file('[Content_Types].xml', fixed)
  return zip.generateAsync({ type: 'arraybuffer' })
}

我也遇到相同问题，用这个解决了
