Você pode tentar isso de aqui :
Windows 7
Show hidden files/folders: By default, our AppData folder is hidden, so we need to show all hidden files and folders before we start.
Open your AppData folder Open your AppData folder, in my case
C:\Users\syahzul\AppData\Roaming\LibreOffice
.Delete LibreOffice Profile: Delete or move all the contents to other place.
Start LibreOffice Once you start the application, LibreOffice will find the profile folder, if not exists it will re-create one for you.
After few days struggling with the issue it [now works]. I hope it works for you too.
É para o LibreOffice, mas você pode tentar.
