Audio/iTunes dependent icons crash after sleep

Describe the bug
A clear and concise description of what the bug is.

It's a little hard to describe, but it appears that the icons detecting whether itunes is playing/ detecting the audio level are crashing after my computer has been sleeping. This is a recent issue (most recent update), and I'm not sure what is causing it. See screenshots.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touch bar
