Thank you for the report! Looking at output, might be duplicate of https://bugs.kde.org/show_bug.cgi?id=486468

Can you try running

gdb amarok
run

and checking if the output is similar to linked bug, i.e.

Thread 1 "amarok" received signal SIGSEGV, Segmentation fault.
vlc_pw_lock (ctx=0x8000000300080005) at modules/audio_output/vlc_pipewire.c:76

gbd debug

Ok ran gbd amarok run | output is 
Thread 1 "amarok" received signal SIGSEGV, Segmentation fault.

Great, thank you!
Interesting, so this is apparently not quite the same issue as the other one.
Could you also try getting a gdb backtrace by running
gdb amarok
run
backtrace

and pasting the out here, please?

Okay, thank you very much!
So although some lines are slightly different, this apparently still is a duplicate of https://bugs.kde.org/show_bug.cgi?id=486468 so marking as such.
There seems to be a potential solution in the latest message of the other bug report, hopefully it fixes the crash for you, too.
