Happens on Amarok master branch, atleast at commit 453aa79e03fc512abcca5b2109a2aecce6dab314 (and most likely older). I did a little digging, and found that it crashes specifically at this line. DiagnosticDialog.cpp - Line 127 aPhononBackend->property( "X-KDE-PhononBackendInfo-Version", QVariant::String ).toString(), // & Backend

Git commit 4ae84cd433864f45b2130c27bca8a2c4c0ba0d5a by Heiko Becker. Committed on 26/03/2020 at 20:21. Pushed by heikobecker into branch 'master'. Fix a crash when trying to open the DiagnosticDialog The possibility to discover the preferred phonon backend is gone since its qt5 port, causing 'KServiceTypeTrader::self()->preferredService( "PhononBackend" )' to return a null pointer, which causes a crash later on. Instead I borrowed some code from the old phonon kcm from plasma-desktop and slightly modified it.
