I think i broke my matlab. A few days ago I seamingly deleted matlabs appdata. (I know stupid).
So i Installed a new version(2021b) becasued i had 2021a. Since then my matlab doesnt work the way it did.
I tried to run this simple code
close all;
clear all;
R = 1;
L = 10e-6;
C = 11e-6;
t_fun = tf([1 0],[L*C*R, L, R]);
bode(t_fun);
title("Übertragungsfunktion");
wich works in matlab online but not on my PC giving me this error
Check for incorrect argument data type or missing argument in call to function 'tf'.
So I am guessing the error comes from this error that I get from starting matlab.
Warning: Executing startup failed in matlabrc.
This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was:
MATLAB:UndefinedFunction
Undefined function 'pm_addunit' for input arguments of type 'char'.
I dont really know what to do here. I deinstalled Matlab2021b and reinstalled it twice already the error wont change. I tried running other simple code on matlab i used to have that works. But i dont really want to be suprised when I use matlab and dont know if the error comes from my faulty code or my broken programm.

Something in your matlabrc is invoking something that tries to use pm_addunit() from the Simscape Physical Modeling Toolbox, but you do not have that toolbox installed.
pm_addunit() adds a new physical unit, so possibly someone thought that was a good idea to have happen automatically for all sessions instead of each project having to initialize the unit.
