version 2.3.2 segmentation faults on Ubuntu 18.04 clicking on My First score in start center

Newly installed MuseScore from repository ppa:mscore-ubuntu/mscore-stable by doing sudo apt-get install musescore.
During installation I saw
/usr/share/mime/packages/gnuradio.xml:1: parser error : Start tag expected, '<' not found
/usr/share/gnuradio/grc/freedesktop/gnuradio-grc.xml
^

Starting musescore from a terminal, as soon as I click "My First Score" in Start Center, Musescore segfaults.
The terminal shows:
initScoreFonts 0x55fb64eefa00
libpng warning: iCCP: known incorrect sRGB profile
Sample::decompressOggVorbis: open failed: Not a valid SNDFILE* pointer.
Segmentation fault (core dumped)
