Obsidian hangs with black screen for large document page

[macin]

Hi,
I have a large document (approx 2.5 MB). I configured Google gemini 1.5 pro and tried generating summary of the text with Text Genreator plugin. The problem is, I get a bllack screen once I run it. Is this scenario supported (i.e. large page?). Can I upload file with the content of the page in any other way?
