Synchronising repository for bundled extensions

LIBRE Office says it has crashed.
Why is my screen flashing this message: Libre Office
Synchronising repository for bundled extensions?
Should I close down my computer?

No need.

If it stalls at synchronizing, you can try to close LO and reset your LibreOffice user profile (rename it).

You’ll have to reinstall the extensions. Personally, I backup the profile to avoid reinstalling it when there is an issue on the profile. Quite rare but just in case.
