Cannot read properties of undefined (reading 'push') (333)

I see that error when try to import manually edited members (batch process):

id	email	name	subscribed_to_emails	complimentary_plan	created_at	labels
621d387d2fe56c1597d0a34d	e@mail.com	name	true	false	2021-08-12T03:00:00.000Z	Cool-label

What can be causing it? I need to remove all the members and try to import on clean way?

EDIT: it seems to be related with encoding:

I had this exact problem, and it brought down my entire system.
I tried zeroing out the members table, but that made no difference. How did you solve the problem?

You can try changing the encoding of the file using a power text editor like Atom or Visual Studio Code.
