Trying to submit a (previously working) channel form as a logged-in user, but returning "Entry Status: Invalid Selection".

Have tried adding hidden field to force entry status.
Have validated default entry status for channel forms in channel settings.

Have tried other channel forms, no issues (including those where "open" is not used as the default channel form status).

Have tried removing all fields, and de-scoping mandatory fields, to submit an otherwise blank form.

How To Reproduce
Don't know!
It's only occurring on one channel form; others seem ok.

Tag looks like:

{exp:channel:form
channel="users_cdata"
include_assets="no"
dynamic_title="Profile - {logged_in_screen_name}"
unique_url_title="yes"
return="/account"
id="pass_check"
class="cpform"
}
...
{/exp:channel:form}
