Assistance Needed: Issue with Running "AoA Detection using MUSIC USRP RIO" Example on USRP-RIO 2955 Devices

Hello, I am currently facing an issue while attempting to use two USRP-RIO 2955 devices to run the NI example "AoA Detection using MUSIC USRP RIO". I have followed the instructions provided by NI, which can be found at "https://forums.ni.com/t5/Software-Defined-Radio/Angle-of-Arrival-Detection-with-NI-USRP-and-LabVIEW/...". However, despite following these instructions, I am encountering a problem as indicated in the following message

" Error -1074118627 occurred at niUSRP Set Time.vi

Possible reason(s):
A runtime or configuration error occurred.
Code: 41
Details: EnvironmentError: IOError: Block ctrl (CE_01_Port_40) no response packet - AssertionError: buff->size() > 0
in unsigned __int64 __cdecl ctrl_iface_impl<0>::wait_for_ack(const bool,const double)
at P:/Measurements/FlexRIO/SWCode/usrp/niuhd2/trunk/19.2/objects/uhdrepo/host/lib/rfnoc/ctrl_iface.cpp:143"

I kindly request the assistance of the NI community in resolving this issue. Any guidance or suggestions to overcome this problem would be greatly appreciated. Thank you in advance for your support.

It would really help us to help you if you post your LabVIEW Code so we can see what you did to cause the error.
