Arduino Uno Unable to Connect. Running on Mac OSx Big Sur on M1 Chip Macbook

I keep trying to connect my Arduino to Matlab and am recieving this error:

"Unable to create a communication link with the serial port. Please check the input argument

PORT and verify that a device is connected."

I am trying to connect using this code:

a = arduino('/dev/tty.usbmodem113201','Uno')

I have confirmed this is the correct port via both terminal and the arduino IDE. The connection is made through a Multi Hub USB to USBC adapter. The connection works properly on the arduino IDE and I am able to run code through the IDE and serial monitor.

Does anyone have any ideas?

I have a very similar issue. I have connected my Arduino board (ATmega328P) through a USB to USB-C adapter (Apple adapter) and I am running Matlab 2019b and get an error:

a = arduino('/dev/cu.usbserial-A400hvsX','Due')

Updating server code on board Due (/dev/cu.usbserial-A400hvsX). This may take a few minutes.

Cannot program board Due (/dev/cu.usbserial-A400hvsX). Please make sure the board is supported and the port and board type are correct. For more information, see Arduino Hardware Troubleshooting.

I have successfully ran scripts from the arduino IDE without problems. I have read about FTDI drivers, but I tried installing one without success. @MathWorks Support Team, your troubleshooting recs fall a bit short. Can you help us?
