I’ve got a weird problem where sometimes when I start to type a heading in Obsidian (one or more # followed by a space) the Obsidian window just goes blank. It’s definitely happened on my Mac, and maybe on Windows though I cannot remember for sure. It’s happened half a dozen times now.
To recover I have to quit and restart Obsidian. Sometimes the heading I was typing is gone, so Obsidian did not save the last few characters I typed.
I suspect it may be something like a plugin crashing, but I don’t know how to troubleshoot it. The last time it happened I tried selecting the View > Toggle Developer Tools in the menu, but nothing happened – the screen stayed blank.
I’m just wondering, the next time this happens what can I do to collect more information and find out what is causing it?
I have done the Rebuild vault cache, to see if that helps.
In the meantime, debug information is as follows:

RECOMMENDATIONS:
Custom theme and snippets: for cosmetic issues, please first try updating your theme and disabling your snippets. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community theme and snippets.
Community plugins: for bugs, please first try updating all your plugins to latest. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community plugins.
```
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.
