Save the kittens!

@MustangGB lol, am I hacking core?

Thanks for reporting and working on this.

It seems to me that this is a bug in the Features module, because according to the list_field_info() the allowed_values settings should be an array. So I think this should be fixed in Features. Core can help with some common PHP8 issues like the ones sending NULL to functions like substr, ...., but this seems to me a bit different case, unless it affects more modules. Generally, core does not "babysit" broken code. Is there an issue in Features module for this? Or why we would like to fix this in core instead of the root cause in Features module? Thanks!

Just hard to view the diff when it's 20k lines long.
