I keep getting the error "Error: File: builtin.m Line: 1 Column: 24 Invalid text character...". How do I fix this?

Hi,
The full error is:
"Error: File: builtin.m Line: 1 Column: 24
Invalid text character. Check for unsupported symbol, invisible character, or pasting of non-ASCII characters."
I get it whenever I try to do anything, including close Matlab. The file name changes slightly depending on what I do: for example, when I try to open a new file, I get the following error:
"Error in matlab.unittest.internal.ui.toolstrip.getFileInfoForToolstrip (line 8)
isClassBasedTest = false;",
preceded by the above text with "false.m" as the file name.
I think the problem started when I tried to set the path? I got the following error:
"Unable to run P-code file. The file header is damaged.
Error in pathtool (line 13)
isDesktop = desktop('-inuse');"
But I'm not sure. Any help that you can give me would be appreciated!

Can you confirm that you haven't defined your own builtin.m function that's taking precedence over the built-in builtin function?
which -all builtin
What do you see when you look at the first line of builtin.m (which ought to contain just the help text for the built-in builtin)?
dbtype 1 builtin.m

It looks like your MATLAB environment has encountered some internal corruption, possibly related to the path settings or some damaged P-code files. You can consider resetting the MATLAB path to its default state by running the following commands:
restoredefaultpath;
rehash toolboxcache;
savepath;
If the error persists, you can try reinstalling MATLAB or connect with the MathWorks support team:
