Cannot open files.

LIbreOffice was running great when I left the country 30 days ago. Upon return and after Win10 system updates, I cannot open any LibreOffice Calc or Writer files. Main dialog comes up, but then Win10 reports LibreOffice is unresponsive after about 30 seconds. Have to use Task Manager to shut it down. I have tried clicking on the file icon in the main Libre dialog, clicking on the file name in Explorer, using File/Open in Libre. I have also tried Safe mode. No luck. I just updated to V5.3.2.2 but still have the same issues. Any ideas?

Try opening this file.
