After changing the file naming script to the following, I couldn't open the preferences again. This is reproducible and when I only remove this setting, the preferences open again.

$noop( $if($eq(%compilation%,1), )
$noop(Various Artist albums)
$noop( Soundtracks/$if2(%albumartist%,%artist%)/%album%/$num(%tracknumber%,2) - %artist% - %title%, )
$noop(Single Artist Albums)
Alben/$if2(%albumartist%,%artist%)/$left(%date%,4) - %album%/$num(%tracknumber%,2) - %title%
$noop( Soundtracks/%album%/$num(%tracknumber%,2) - %title% )
)

I see the error that everything is in one $noop() command, but I think the preferences should open anyway.
