IDE fatal error regularly occurring in Idea 2018.1 EAP

Since updating to the new IDEA Ultimate 2018.1 EAP when it was released a week or two ago, I regularly get this exception occurring:

2 intention duplicates found for com.vladsch.idea.multimarkdown.intentions.flexmark.ToggleFlexmarkExampleIgnoreIntention@15c0a31a]

It shows up as a core IDE bug so it only lets me submit it to JetBrains, but I’m pretty sure it’s gotta be related to Markdown Navigator.

This occurs in both Windows 10 and Elementary OS on the latest EAP release (I update daily as new releases are available, and the issue has been consistent since the first 2018.1 EAP release through the latest one).

@bdonkey, sorry forgot to include the customary instructions:

To enable EAP update channel:

Then make the IDE check for updates.
