Critical error when importing users from CSV file

Hi there!

First of all, thanks for this great plugin!

After the latest update, I could not import users using a CSV file anymore and I’m getting the following a critical WordPress error instead:

PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 57671792 bytes) in /…/wp-includes/wp-db.php on line 3006

The CSV file format I’m using -which worked with no issues before- is:

Username | Email | Password | last_name | first_name

My site is currently running:

• Import and export users and customers on v1.19.1.9
• WordPress on v5.8.1

Please, let me know if you need any further info.

Thanks in advance!
