Pycharm Markdown Preview displays CSS code instead of rendered content
Answered
The PyCharm (or another JetBrains IDE with the Markdown plugin) Markdown Preview pane is failing to render the markdown content of a .md file. Instead of displaying the formatted text, it shows raw CSS styling code. This occurs consistently whenever a markdown file is opened and the preview pane is visible.
The CSS code displayed appears to be from the preview's own internal styling rules, specifically for a context menu and info box. The preview is completely unusable as a result.
I run PyCharm 2025.2 (252.23892.439) on Windows 11.
I would be very grateful for any help!

Both 2025.2 community and normal versions - preview pane not functioning on Ubuntu 24 - showing blank.
