Error when running run section

I get this error when I run: "run section" from the editor tab

Error using builtin
Must be a text scalar.
Error in matlab.internal.editor.eval.TempFolder/get.CurrentFolder
Error in matlab.internal.editor.eval.TempFolder/getFolderOnPath
Error in matlab.internal.editor.eval.TmpFilePath.get
Error in matlab.internal.editor.evaluateCode

However, if I run the code in that section using "Evaluate selection" it works fine.

Thank you

In general, executing the cell modes of scripts is more sensitive on syntax errors made in other sections sections of the code. Executing the selected section of the code doesn't encount the rest of the code.

From your prompted errors, it looks like that you have some errs in other sections of your script. Scan your code and you will see red highlights on the left sidebar of the editor.

this is not my problem. I try with the following simple script:

%% 1 section
a = 10+5;
%% 2 section
b = 4+6;

and when I try to run one of the section with "Run section" I still have the same error:

Error using builtin
Must be a text scalar.

Error in matlab.internal.editor.eval.TempFolder/get.CurrentFolder

Error in matlab.internal.editor.eval.TempFolder/getFolderOnPath

Error in matlab.internal.editor.eval.TmpFilePath.get

Error in matlab.internal.editor.evaluateCode

Unfortunately the appropriate function has been p'coded and we cannot look at the source.

As an experiment, try

restoredefaultpath; rehash toolboxcache

and see if the problem goes away. If it does, then you have some third-party code on your MATLAB path that is interfering with the function.

[Maria Lazzaroni]

That works! I will figure out the interfering function. Thanks!

is matlab addressing/fixing this issue? syntax errors in other sections should not affect the ability to execute code in given section.
