RunTimeError, Tkinter и мультипоточность

Создаю чат-сервер на socket и threading + tkinter Использую TCP/IP, server <-> client

Как я понял ошибка из-за особеностей ткинтера, но всё решения что я нашел в сети были индивидуальними.

Сама ошибка:

Exception in thread SendThread:
Traceback (most recent call last):
