Am unable to validate if it still happens on tvOS 15.5 betas, since this crash still only happened in production with versions 15.4 and 15.4.1.
Unfortunately was unable to get a full symbolicated crash report from the analytics platform being used. For some reason, this same crash is not showing up in Xcode Organiser section. However, if there's a specific info you're looking for, please let me know, since I may still be able to get it.
