Project build fails

Receiving an error response that project build fails and never complete. Both by UI and by API call. What can be the reason? Project is small, about 800 stings, MS Word files only.

It’s a tag question. In a translation, some proofreader or manager saved translation that has wrong tag or something like that. They can press save anyway button even if QA check says that something is wrong. Go to editor, search for a strings that were recently translated, one or few of them need correction with a translation that has a proper amount of tags (to match the source)
