Error when using 'Run Section'

I get the following error whenever I click on Run section.

If i run the entire script the it works fine.

If i select individual snipets of code then it still works fine. Only run section produces this error. The same error no matter hat code i am runnng.

I have windows 10 and MATLAB 2020a.

P.S. I have 2020a installed on my other computers and they work just fine.

the problem is only on this computer. I installed MATLAB two weeks ago and the probem is since the starting.

What does which('randi','-all') return?

It returns the following:

>> which('randi','-all')

Remove the randi function here from your path:

C:\Users\maris\Desktop\Bachelor Thesis\mvgc_v1.0\mvgc_v1.0\utils\legacy\randi\randi.m

Either rename the file, delete it, or remove the folder from your path.

For an explanation of why it is a bad habit to shadow the names of internal functions, see this thread. As you see, stuff tends to break at some point.

I just removed the function from the path and this happened:

Error using matlab.internal.editor.eval.FileInfo
Invalid default value for property 'Salt' in class 'matlab.internal.editor.eval.TempFolder':
Previously accessible file "C:\Users\maris\Desktop\Bachelor Thesis\mvgc_v1.0\mvgc_v1.0\utils\legacy\randi\randi.m" is now inaccessible.
