Cannot uninstall - Fields pending deletion

Solution #10 worked for me too

The Drush command from the README gives an error:

$ drush ypu
  Command "ypu" is not defined.
Failed to run drush ypu: exit status 1

It looks like the module adds a "Meta tags"-field to content types. I deleted them manually, after which the configuration was the same as before installing the module. For example /admin/structure/types/manage/page/fields/node.page.field_meta_tags/delete.

HOW TO UNINSTALL YOUR MODULE??? I CANNOT EVEN PUBLISH ANYTHING!!

yoast_seo: The Real-time SEO status & focused keywords field type is used in the following field: node.field_y
oast_seo

I tried solution #10 and got an error message:
Attempted to create an instance of field with name bp_background on entity type paragraph when the field storage does not exist.
So the fields were not getting purged because there was an accidental deletion of the "bp_background" field's table in the database. After looking all through the Paragraph module, I finally realised that this field was created by the "Bootstrap Paragraphs" module, which I had uninstalled. I re-installed it, ran the drush php-eval 'field_purge_batch(500);' command, got no errors, and then I could uninstall this module.

Documenting this in case it helps someone else find the problem sooner.

i am trying solution #10 and i am getting this issue
Value must be NULL, an instance of EntityInterface, or an array with "target_id" and "target_revision_id".
