Crash upon Selecting Theme

Hello,

There seems to be some problem (bug?) when I try to change the theme of LibreOffice

Tools > Option > Personalization > Select Theme > I click on a Categorie and then a “Searching, please wait…” message appears but no options are loaded and then LibreOffice crashes

Windows 10

LibreOffice Version: 6.0.5.2 (x64)
Build ID: 54c8cbb85f300ac59db32fe8a675ff7683cd5a16
