Problem with importing users using library WTelegramClient

Question

1. Follow this link: https://github.com/wiz0u/WTelegramClient , downloaded the project: wtelgramclienttestwf.
2. On the main form, I added a ordinary button with a description: import users
3. For the "import users" button - added an event on a click.
4. Then I added a method for importing users.
5. In this method, I pass the phone number of the desired client
6. Accordingly, when I turn to the method: Contacts_ImportContacts - the studio just freezes and does not respond.
7. There are no mistakes.
8. For understanding, also see the uploaded photos.

Sorry but we don't have enough elements to answer you.

Surround the API call with try..catch, maybe you have an exception.
