Can I use MATLAB Compiler to create a standalone app for controlling a Simulink Real-Time application in R2020b and later?

I migrated to MATLAB R2020b. I created an App Designer instrument panel app to control my real-time application running on a Speedgoat machine, similar to the following:
However, when I deploy this app to a standalone executable using MATLAB Compiler and try to execute this standalone GUI, I get the following error:
Invalid default value for property 'tg' in class 'App':
Undefined function 'slrealtime' for input arguments of type 'char'.

From R2021b onwards, you can use MATLAB Compiler to create a standalone executable for controlling real-time applications. You can deploy instrument panels created with App Designer, or simple MATLAB programs that use the MATLAB API for Simulink Real-Time (SLRT). For a basic example, see: Create Standalone Instrument Panel App by Using Application Compiler
By using the MATLAB Compiler workflow, the end user does not require any MATLAB license to interact with the Speedgoat target computer. The SLRT app will run against the royalty-free MATLAB Runtime.
For designing an app tailored to your real-time applications, and things to keep in mind for deployment, the following MATLAB Answers are a good starting point:
Note that Simulink Compiler is not required for this workflow.
