Execution of script fzero as a function is not supported:<current folder path>

You've somehow got an alias script file named fzero on the MATLABPATH.

What does

which -all fzero

return?

It should be something like

>> which -all fzero
C:\ML_R2020b\toolbox\matlab\optimfun\fzero.m
>>

with your own installation root directory, of course.

If there's another fzero, either rename it to something else like my_fzero.m or remove it and all should be well...

which -all fzero
