Thanks Geez, holding down the radio allowed me to finish the tutorial, as you instructed. However, no message played for me over the radio; it was silent. Must be an issue with the audio file on my system or something.

I've got a very similar issue; not sure if it's the same one. This issue only appeared for me after the last update. I'm on Fedora 36, running Proton 7.0-4 (issue persists with Experimental as well).
Video of the issue attached below.
