I use MATLAB online, the initial toolboxes are all already installed and cant be uninstalled
[H, F] = freqz(b , a, 512, Fe);
freqz requires one of the following:
Audio Toolbox
Communications Toolbox
DSP System Toolbox
Signal Processing Toolbox
Wavelet Toolbox

You can check if the license for Signal Processing Toolbox exists and is in use by executing the following commands in the MATLAB Command Window:
>> license('test','signal_toolbox')
>> license('inuse','signal_toolbox')
If it exists, and is not in use, you can check it out using the following code:
[status,errmsg] = license('checkout','signal_toolbox')
Refer to this documentaton for more information:

I suspect you may have connected to a bad worker. Creating a new session will connect you to a new worker, and should fix the issue. If not, then there may be a temporary outage impacting the experience. Those tend to be resolved relatively quickly.
If you continue to have issues, please contact support: https://www.mathworks.com/support/contact_us.html

The current recommendation is the exit your session and then launch a new session. There is an intermitent issue, so until a fix is in place, you may need to do this multiple times before you get a good session.
