Consider a model M with a one2many field with comodel L, such that deleting records in M cascade-deletes records in L. Import a bunch of records in M with one2many lines having specific external ids. Delete the imported records: the database cascade-deletes the corresponding lines, but the lines' external ids are not deleted. Now re-import the same records: this crashes, because the import process finds the lines' external ids and tries to update the deleted lines! The fix consists in checking that an external id's record actually exists. The existence check was removed for performance reasons by https://github.com/odoo/odoo/pull/26496. We reintroduce it by resolving the external id with a join on the model's name, which checks the record's existence faster than an extra query. This patch allows to re-create the imported records' lines. Another patch is necessary to actually update the external ids that refer to deleted records, otherwise they remain dangling, and importing the same records again duplicates the lines, because their external ids do not match any existing record.
