Hi,
I’m having the same issue.
I was able to open a new document and insert a reference successfully so I followed the first link as you recommended.
Unfortunately when I try to “format this cleaned up version of the document without running into problems” I very much run into problems as it just crashes windows again each time I click ‘Update Citations and Bibliography’.
I had added references to the document many times without any issues, including several times only minutes before the issue occurred.
Any help would be very appreciated.
Best
