What does "Interrupt while evaluating Button PrivateButtonPushedFcn." mean?

My program was working but now I'm getting this.

Interrupt while evaluating Button PrivateButtonPushedFcn.

If I knew more about the error maybe I coud fix it. There is no help looking up this error in MatLab help. Googled but got trivial problems others had had.

Hi Gavin,

you can take a look into this similar kind of issue related to "Interrupt error": https://in.mathworks.com/matlabcentral/answers/432042

or else if possible could you eplain the issue in more details?

It means that you pressed control-C while the callback for PrivateButtonPushedFcn was active.

I did not press Ctrl-C but I was possibly at a breakpoint in the debugger.

I'm having trouble because unless you are paused at a breakpoint you can't see any values of variables or handles.

>> app.DebugField.Value

Unable to resolve the name 'app.DebugField.Value'.

>> toPicoStr

Unrecognized function or variable 'toPicoStr'.

Nothing can be seen while the program is running and not halted somewhere. There is probably a reason but I's sure like to track variables without having to set a random breakpoint to get a halt.
