Sorry but I cannot reproduce this issue.

Can only confirm that vuepress 1.x docs site failed in ie 11.

Seem that codes from 3rd party packages are not transpiled correctly (e.g. vuepress-plugin-flowchart, vuepress-plugin-smooth-scroll, etc.)

#2064 can partially fix the failure in IE 11.

But Object.assign is still not polyfilled.
