Matlab AppData Folder making problems after renaming User and Path because of problems with an apostrophe

Hello dear community,

i am facing a problem and i can´t find a solution to it.

My name has an apostrophe ó. Years ago, when i got my Laptop i did not know, that this coud create problems so i named it with the apostrophe. Because i was experiencing problems with the Matlab Support Package for LEGO EV3 while building i changed the User name and also all Paths within C://.

I uninstalled Matlab and all Packages and reinstalled it with the new username and renamed paths.

But when i try to bild Matlab creates a new user with the Apostrophe and in there there are several folders -> User -> AppData -> Roaming -> MathwWorks -> Matlab -> R2021a -> LightweightBrowser -> jcef_cache -> and then a couple of files and more folders.

Because of this i think i get an error message as follows, when i try to run the software in external mode:

Created: ../Gyrosensor_test" "### Successfully generated all binary outputs." ### Downloading the application to EV3 ... ### Successful completion of build procedure for: Gyrosensor_test ### Simulink cache artifacts for 'Gyrosensor_test' were created in 'C:\Users\Gyrosensor_test.slxc'.

Build process completed successfully

Build Summary

1

Elapsed: 0.30 sec

Top model targets built: Model Action Rebuild Reason ================================================================================================ Gyrosensor_test Code generated and compiled Code generation information file does not exist. 1 of 1 models built (0 models already up to date) Build duration: 0h 1m 13.795s

Saving external mode simulation output as a single object is not supported because the workspace variable 'out' is not created during model code execution. To suppress the warning, set 'ReturnWorkspaceOutputs' to 'off'.

Component: Simulink | Category: Model warning

External Mode Open Protocol CheckData command failed

Caused by:

• Multiple errors detected.
• XCP Master internal error: Busy(0) or no timeout(2) for 252
• Error detected while trying to disconnect Simulink from target application.
• Error returned by XCP master: XCP Master internal error: No slave connected

Does someone have a solution to this problem and could it be possible, that it is because of the folder that i mentioned?

I have been getting a Dwarf parse error too...

Greetings Ramón

Clear all;

close all;

f=input('/n input Function (dR/dt)= ');

t0=input('/n enter initial value of t(t0)=');

R0= input ('/n enter initial value of R(R0)=');

h= input('/n enter steps(h)=');

tg=input('/n enter final value of t(tg)=');

n=(tg-to)/h;

For i=1:n

Rg=R0+h*f(t0,R0);

t0= t0+h;

R0=Rg;

fprintf('/n Rg=%f',Rg);
