Question

I need this part of script work infinitely(send messages), but it works only one time and then stops

f = open('text.txt')
t = 1
with app:
    while True:
        for line in f.readlines():
            try:
                app.send_message(chat_id=line[13:].rstrip(), text=txt)
                print(f"Успешно написал в чат по ссылке {line}")
                time.sleep(0.5)
            except:
                print(f"Что-то пошло не так... Возможно в чате {line} включен медленный режим")```

The for loop stops when it gets to the end of the file. When the while loop repeats, there's nothing for the for loop to read because you're already at the end of the file.

You can seek to the beginning each time.

f = open('text.txt')
t = 1
with app:
    while True:
        f.seek(0)
        for line in f.readlines():
            try:
                app.send_message(chat_id=line[13:].rstrip(), text=txt)
                print(f"Успешно написал в чат по ссылке {line}")
                time.sleep(0.5)
            except:
                print(f"Что-то пошло не так... Возможно в чате {line} включен медленный режим")     

Or you could save the contents to a list and loop through that.

with open('text.txt') as f:
    lines = f.readlines()
t = 1
with app:
    while True:
        for line in lines:
            try:
                app.send_message(chat_id=line[13:].rstrip(), text=txt)
                print(f"Успешно написал в чат по ссылке {line}")
                time.sleep(0.5)
            except:
                print(f"Что-то пошло не так... Возможно в чате {line} включен медленный режим")
