So it seems that my laptop has downloaded the wrong fplot. It had downloaded the regular fplot that plot expression or function however I need the one that plots symbolic expression or function. I have uninstalled matlab and reinstalled it however it still downloaded the wrong one. What do I do?

Show us which fplot functions you have available.
which -all fplot
Also call the ver function and tell us if Symbolic Math Toolbox is listed in its output.

Delete or rename the one that you have in OneDrive, or use pathtool to move your OneDrive folder to the end of the list of paths.
