When attempting to preview .md files using Ctrl + Shift + V, the preview pane opens but remains completely empty. This occurs on all Markdown files, regardless of content.

Steps to Reproduce

  1. Open any .md file in the editor.
  2. Press Ctrl + Shift + V to open the Markdown preview.
  3. The preview pane appears, but it is completely blank.

Additional Notes

  • Restarting the editor does not fix the issue.
  • Issue persists across different workspaces and files.
  • Error appear in the console:
    Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'sha256-P2eVBRNqvNBb9eWklx8rKTilnjxyAEeUd4xaprd12XE=' 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-DBmpO7fNgmVb4FnA7cax3H6VOiFKkE02jFkm2NcSm6o='), or a nonce ('nonce-...') is required to enable inline execution.

I found the solution. I will reply myself. You need to go to configure the default editor for ‘.mdc’ and change it to use the Text Editor instead of the MDC Editor
