This is a known bug with no known fix. See this topic in the official Adobe feedback forum: Lightroom: Can't access the Export dialogue. Please add your vote and details about your issue to this topic -- that will make it a little more likely Adobe will prioritize a fix. Two senior Adobe employees are participating in that topic, so your feedback will be noticed.
