Unable to Open Open Office spreadsheet on Windows 10

It used to work fine a few months ago. So it must be one of the Win 10 updates.

When I click on the .ods file, Open Office flashes up and then closes. If I start Open Office from its shortcut on the desktop and select the same file, it works fine.

I have done these things, but no luck.

1. Deleted the Open Office profile
2. Repaired the install.
3. Removed and Re-installed it.

Any other suggestions ?
