File freezes LO Writer

As happens at some point with every book I write, my latest manuscript freezes and won’t open at all. Can someone take a look and see if it will open on a different OS to Windows 10. I can send it in a private message. I back up every hour or so, but I really don’t want to have to remember all the changes I made in the last hour if it can be avoided. But above all, I’d like to know why I always have this issue. For years, and with every version I’ve used during that time. It usually starts when I link images or update indexes. Thanks.

EDIT: Ajlittoz kindly checked the file for me and it opened correctly on his Linux system. I resolved my issue by starting over inserting images and so far no problems.

Indeed, then it opens. I suspected the Zotero add-on, so uninstalled that. Turns out that wasn’t the miscreant.
