MALTAB standalone desktop app deployment has error: how to identify the error message?

I used MATLAB compiler to package my App designed using Appdesigner. This is the first time I tried to deploy my app using stand alone packaging.

I have compiled an executable and sent it to a colleague who is having trouble after successfully installed the app.

After run the app, at the step of input, there is an error message sound. But there is no way to see any error message.

I am using R2020b. both mine and my colleagues's machien is Win10.

Have your app create a log file. See this answer for how to do that. Run the app until the error is encountered, then check the log file to see what the error messages are.
