I understand that MATLAB throws the error "The import tool does not have access to read the file" when you are trying to import CSV files using the Import tool.
Please try to restore the default path and rehash the toolbox cache by running the following commands and restarting MATLAB:
>>restoredefaultpath
>>rehash toolboxcache
If the issue persists, try the following workarounds:
1) Check whether there are files such as an "h.m" in the current directory. Try importing the file from an otherwise empty directory.
2) You can call the function "load" which can store the file as an array:
>> variable = load(filename)
3) You can also use the function "csvread" to load/import data. However, note that this will not work for empty CSV files.
>> variable = csvread(filename)
