Crash when playing downloaded 1080p Premium and default quality set

[employee-brokers-bailed]

Describe the bug

If you use YouTube Premium's download feature to download a video with 1080p Premium at 1080p, it downloads the 1080p Premium version (based on Stats for Nerds when playing the downloaded video). If you have either of the default quality settings set to anything other than "default", playing one of these downloaded videos causes a crash. Setting both Wi-Fi and cellular to "default" prevents the crash. ytp_5.2.1+21.16.2.ipa.

I can get a full crashlog but here is the one from LiveContainer which I'm assuming is enough and this is a fairly clear bug from missing a string or something. I can also give you more context on what some of the Obj-C methods give if you don't have YouTube Premium if it's not though.
