I appear to be getting the same error. It started when I upgraded to PyCharm 2019.3.1. Using a simple project (attached) with only one md file, I was able to recreate the problem.

With the gfm plugin installed and enabled the problem manifests itself two ways.

1. Start PyCharm with no projects open or with a previously opened project that has no markdown (extension .md) files open.

   a. Create a new project or open a project that has all markdown files closed.

   b. Create or open a markdown file.

   c. By default, the file is shown with the Markdown split editor selected.

   d. Click on the Gfm Preview tab at the bottom.

   e. At this point a java runtime exception has occured. (Click on the blinking red circle with the white exclamation point in the lower right hand corner to see the stack trace.)

2. Start PyCharm with a previously opened project that has a markdown file open.

   a. When PyCharm completes all its indexing, it will immediately abnormally terminate. (To escape from this viscous cycle, delete the gfm-plugin directory form the repository of plugins. On the mac it is ~/Library/Aplication Support/PyCharmxxx.)

Notes:

• This behavior is the same for both PyCharm Professional and PyCharm Community Edition.
• The testing with PyCharmCE had no other plugins (other than the bundled ones) installed.

Attached is a copy of the simple project that includes all the stack traces, Apple reports, PyCharm About text, and plugin info. If you need more info, please let me know.
