App Designer has suddendly stopped recognising the string() function.

Previously stable parts of code in my script have stopped working because Matlab seems to have forgotten what string() is.

Autocomplete still suggests it when typing but the error presists even when the I use the autocomplete. Its not isolated to this line. If commented out the next string() throws the error.

I've restarted Matlab and the the PC. No joy.

String() does work in new scripts in both Matlab and the app designer.

Does anyone know whats going on?

**Update

So retracing my steps and mashing buttons, I believe i've found the cause.

I was try to populate a table from filedata and encoutered this error:

Foolishly I tried to cast the cell as a string() (Mechanical engineer by trade. I'm no expert)

When this casting attempt is removed the script returns to normal behaviour.

I hope this helps anyone who makes the same mistake.
