Obsidian window goes blank when typing a heading

The full troubleshooting guide is here: https://forum.obsidian.md/t/about-the-bug-reports-category/24/11.

No need to file a bug report yet, but looking at your debug info I’d go to Settings > Community plugins > Restricted mode and click Turn on and reload. The issue is probably not from a snippet, but I’d disable those as well for testing.

If you don’t see the issue in Restricted mode, it’s coming from one of your plugins. Turn Restricted mode OFF (enabling community plugins), disable all the plugins individually, and restart. You don’t have that many so you can slowly turn one on at a time to see how it goes for a hour or so. No problem → enable another and so on.
