Coming back to this, I don’t know what’s actually happening. I reopened everything again, and when editing that same note I was editing, suddenly Obsidian will again hang. Just adding one word, literally. I first thought it was related to me migrating today my Vault to iCloud Drive (I was tempted to use the Mobile app on my iPad), but I immediately excluded that issue by using the original Vault.
As I am writing this, Obsidian sits next to me, is unresponsive, and I see it is using 100% CPU. I see no error messages. I hope it won’t turn into being unstable suddenly, as it would seriously break things for me.
Update: OK, it’s really weird. I can exit Obsidian from the menu (MacOS here). I now moved .obsidian/workspace* out of the way, and could restart. I went back to my note, and typed three words, and boom. It again hangs.
I had the Developer tools open this time, but they show nothing.
It was hanging right after the citation plugin. I’ve no idea what that plugin doesn’t like; the bibtex library opens no problem with Bibdesk. Anyway, after that, it went further, the vault did open without moving the workspace* out of the way.
Then I again continue typing like three words into my note, and everything again hangs.
I think I found, though did not understand what has happened. In the note I had a simple link to another note:
[[Niklas Luhman Archiv]]
You can see that from my screen shot. As soon as I removed that link, I could then continue editing (after the obvious restart). In other words, I killed Obsidian, went into the markdown file with some editor, removed that link, and then relaunched obsidian.
I could edit as much as I want now, even after re-adding that link
Unfortunately I wasn’t able to capture any good logs of this behavior, but it is scary.
