The failure comes from `rb_intern3 -> sym_find_or_insert_static_symbol` (during Prism parsing).

03:56 PM Ruby Bug #21670: 3.4.5 crashing with "try to mark T_NONE object"

It's in `mark_method_entry_i`, which rings a bell. @jhawthorn didn't you fix that one?
@esaron please try the latest patch release: 3.4.7, your issue looks a lot like a missing write barrier issue and John fixed many of them in 3.4.7:... byroot (Jean Boussier)
