I did assume it was Windows 11 Home that caused the problem.
But let’s start again from the beginning.
If you are using Windows 11 Home:
Windows 11 S mode is a version of Windows 11 that is specially designed to improve security and performance. It limits the installation of apps only from the Microsoft Store, which reduces security risks. In S mode, Windows 11 is only available as a Home version.
One-way switch:
Leaving S mode is a permanent action and you cannot go back to S mode.
How to exit S mode?
Open the Microsoft Store
Go to the page where you can exit S mode (Switch out of S mode)
Select “Get”
When the confirmation message appears, you can also install apps from sources other than the Microsoft Store.
Once the above is done:
If you are having problems with your installed LibreOffice software, I recommend that you follow these instructions:
Type services.msc in the taskbar search box, click the services.msc icon that appears at the top. Search LibreOffice Maintenace Service from the list, right click on it and select properties, if running shut it down. Select Not in use for Start method in the dropdown box, click Appy, Ok and close the window. Right clik on the taskbar and select Taskmanager, select the Startup Applications tab, select LibreOffice, right click and disable. Now restart your computer and uninstall LibreOffice. Navigate to C:\Users\yourprofilename\AppData\Roaming and delete LibreOffice folder.
Download LibreOffice .msi installer, right-click on the file icon, select “Properties”, go to the “General” tab, and check the “Allow” box on the right down corner, Click the “Apply” button to save the changes and remove the security restriction. Click “OK” to close close the Properties window and click the .msi installer icon to install.
I guarantee that your Windows Home & LibreOffice problems will go away. Instead, I am 100% sure that no changes to LibreOffice settings will fix the problems with Windows 11 Home and LibreOffice installed from the .msi package.
