Whenever I type a left curly brace in my LaTeX document, the editor crashes. It crashes when copy-pasting the curly brace, too. This happens on two different computers, with just one file. I've tried changing the directory, creating a new file with the same content, updating TeX Live, but nothing works. The only thing that comes to my mind is that the document is pretty big, because it's almost 12000 code lines and 95 pages. Is this an issue? I'm not particularly experienced with LaTeX. What should I do?
Edit: downloaded TeXstudio and had no issues. How is this possible? I thought TeXmaker was the best editor.
