I am getting the following warning when building a model for Simulink RealTime:

Warning: This model contains blocks that do not handle sample time
changes at runtime. To avoid incorrect results, only change
the sample time in the original model, then rebuild the model. 

There are no other warnings when building the model. How can I find which block(s) are responsible for this warning or the reason for the warning?

More Info:

I am using the following system target file:

System Target File: C:\Program Files\MATLAB\R2019a\toolbox\slrt\rtw\slrt.tlc

I am using the Microsoft Visual C++ 2019 (C) compiler

The warning is generated by the following private function:

function xpcSampleTimeWarning
% Simulink Real-Time private function
% Copyright 2008 The MathWorks, Inc.
warning(message('xPCTarget:sampleTime:sampleTimeInvariance'));

Runing various model advisor checks yielded no help.
