Syms suddenly doesnt work

Something what I have done many times and something that is in matlab helt suddently doesnt work? any idea how that is. Link to matlab help site: https://se.mathworks.com/help/symbolic/syms.html, look under "Create Vector of Symbolic Scalar Variables"

syms c [1 4]

And I get this error:

Warning: deprecated syntax used in sym constructor

> In sym (line 156)

In syms (line 56)

Error using assignin

Invalid variable name "[1 4]" in ASSIGNIN.

Error in syms (line 56)

assignin('caller',varargin{i},sym(varargin{i}));

[Walter Roberson]

Line 56 of syms in R2023b is comments -- the comments go to line 97.

Therefore, you are not using the regular syms code.

Perhaps you installed MATLAB Connector for Maple?

I did install MATLAB Connector for Maple, but i had no clue that it impacted matlab in such a way, really dont think that is clear.
