Security check from macOS High Sierra tells "LibreOffice.app is damaged and cannot be opened" after its installation and the installation of French locales.
1) what are your Gatekeeper settings ?
2) Can you try running the following command from the Terminal and then attempt to start LibreOffice :
xattr -d com.apple.quarantine /Applications/LibreOffice.app
Please report back your findings here.
So, I could reproduce this with LO5451...
Note that I already had a functioning LO5432 with FR langpack.
1) I downloaded the main DMG plus the FR langpack.
2) I installed the main LO app bundle in the usual way, by drag and drop into the Applications folder. I authorized the installer to overwrite my existing LibreOffice.app
3) I then installed the langpack, and authorized it to install (admin password).
4) I then tried starting LibreOffice.app directly from the Applications folder via a double-click of the mouse.
5) At this point, an error message is displayed indicating that the installation is corrupt and that I should move the app to the trash.
I removed LO and started again, however, this time, I started the main app bundle after its installation by right mouse button clicking on the app and choosing Open from the context menu, BEFORE installing the langpack. After closing the LO app launched for the first time, I then installed the langpack and restarted LO. Everything worked as normal by proceeding in this manner.
@cloph : there's something still not right here with the installation process, but I can't nail it down. When the langpack is installed, it is supposed to start LO for a first time - it did indeed appear to do this, as there is activity in the Dock, but launching LibreOffice.app from the Applications folder after this caused the "corrupt application" error message to appear.
So, if I check the app bundle with
codesign -vvv /Applications/LibreOffice.app
/Applications/LibreOffice.app: a sealed resource is missing or invalid
file added: /Applications/LibreOffice 2.app/Contents/Resources/autotext/fr/crdbus50.bau
with the same message for the usual list of other files that get added when the langpack is installed
Gatekeeper is set to allow apps from the AppStore and identified developers.

I should corrected the output above : LibreOffice 2.app to LibreOffice.app. I have several installations of LO under various names, but the problem remains the same irrespective of that.
My Gatekeeper settings are :
"allow apps from the AppStore and identified developers"
LibreOffice 188.8.131.52 works again after entering the terminal command you provided.
Sorry for this late reply, i didn't see your follow up.
