Page locked due to memory issue

I have a file with 10 pages. Out of the blue one of the pages is no longer accesible and shows the message “File out of memory” when I try to access it. Everything else is working perfectly it’s just that one page. I tried recovering an older version of the file to fix it but the screen gets stuck on the loading page every time I try to do this. Has anyone else encountered this problem, and if so how did you fix it? How can I access the page so I can at least recover and copy paste the content into another file? Any help would be very much appreciated.

I’m working on the desktop app on Mac.

Remove everything from other pages first, reload the file to free up memory & cache, then open the page that is too big.

If that doesn’t work, when you use version history and it gets stuck, right click the tab and select Reload, this usually helps.
