Description:
I installed latest 6.0.4 from 6.0.2, it warned it was replacing files in use and I would have to restart Windows 10. I did so, then the first thing I did was check if I had the latest version. Check for Updates didn't look or operate right.

Steps to Reproduce:
1. Install new version
2. Start LibreOffice (the hub, not a particular app)
3. From the window of recent documents, choose Help > Check for Updates

Actual Results:  
Check for Updates window appeared, displaying Checking..., a spinner, %PERCENT% and with all buttons clickable (attachment coming). It never progressed from this.

Expected Results:
Check for Updates should have worked normally, there was nothing special apart from this being my first action with the new build.


Reproducible: Couldn't Reproduce


User Profile Reset: No



Additional Info:
I quit LibreOffice, then restarted it and chose Check for Updates again. This time after a split-second seeing the spinner, the expected "LibreOffice 6.0 is up to date" appeared with buttons appropriately deactivated.

I hope someone else can try this as the very first thing after installing an update.
