Following your suggestion, I am able to preview the latex snippets without any issue. I also tried removing org-fragtog from my config and previewing manually; I still get an org-element-cache error. I haven't yet seen emacs hang without org-fragtog, but I suspect that that is just because the latex previews are happening less frequently because I'm triggering them manually. Not sure.

I take class notes using latex. I use org-fragtog to automatically preview inline latex snippets as I type. My org documents are usually

full of small snippets of latex: — E.G.:

Basic Addition

$5+5 = 5\( — Lately, whenever I write a new latex snippet and move my cursor outside the two dollar signs, instead of rendering the latex, my entire emacs instance hangs. I then have to run "pkill emacs", restart the daemon, go back in and run "recover-this-file" to continue my work.

Thanks for the report! Does the problem happen if you run emacs without your config and toggle latex preview? (emacs -Q)
