Document editor crashes immediately after I opened a DOCX or ODT file

The document editor crashes immediately after I opened or created a .docx file, or a .odt file, sending me back to the main page. Other readers / editors, including chart editor, presentation editor, and pdf reader, works fine.

I can offer a screen record if needed, but I can’t due to new user limitation.

Strangely, the problem disappeared after I cleared the software cache once, and I haven’t been able to reproduce it since then.
