This issue only seems to happen when I access the audio library, select Roblox as the creator, and then click on an audio. This issue is happening 100% of the time for me whenever I click any of the audios on the first page and then click the back button.
Here is a GIF that shows the steps I used to find this bug.

Before that, I went on to the Create tab, then library, then selected the audio section.
Here is another GIF that shows how I got there from the home screen.

Again, this bug seems to happen 100% of the time, even though the page that I am going back to still exists.
