TelegramBot cannot receive and show a list of Responsible people

[nekludovv]

Since May 2023 I have been using TelegramBot_2_0_0_dev_24_05_2023. You sent me this version individually. See the E-mail.

Версия MantisBT 2.25.7
Версия схемы 211
Версия PHP 7.3.33
Драйвер базы данных mysqli
Версия база данных, описание 10.11.2, 10.11.2-MariaDB

Something happened a couple of days ago. When creating a task, it cannot receive and show a list of Responsible people in the chat. After entering the the algorithm freezes, nothing happens in the Telegram chat.

I try to get out of the hang, enter any character in the input Field, the algorithm works further to the end.

I receive the created task as a new one without assigning anyone.

Errors

I switched on
$g_display_errors = array(

• E_WARNING           => DISPLAY_ERROR_HALT,
  

• E_ALL               => DISPLAY_ERROR_INLINE,
  

• );
  

In the /tmp/TelegramBot_debug.log file, there are 400 Bad Requests for these requests

< HTTP/1.1 400 Bad Request
< Server: nginx/1.18.0

• HTTP error before end of send, stop sending
  <
• Closing connection 0

Is this due to the fact that the list of users is large - 187?
What could have happened?
How to fix it?

The rest of the Telegram Bot functionality works fine.

P.S.
A couple of days ago I tried to install a new version of Mantis 2.26. TelegramBot did not work. I rolled away. Showed an error by type INTERNAL APPLICATION ERROR #32

Is TelegramBot_2_0_0_dev_24_05_2023 compatible with Mantis 2.26?
Could Mantis 2.26 have written anything to the database?

TelegramBot has worked properly.
I was setting the parameters:
$g_show_user_realname_threshold = ANYBODY;
$g_show_realname = ON;
