I can't read a .txt using importdata, but it works for .jpg or .xlsx

I use the MATLAB r2016b for mac. I tried to use the 'importdata' to read a .txt file, even the text is simple enough, I can still get the 'MATLAB has encountered an internal problem and needs to close' warning. I tried to use it on a .jpg or .xlsx, it both works well. Why it refused to work on a simple .txt file like,

# a b c

1 2 3

5 6 7

Is anyone facing the same problem? Is there any good solutions? Thank you very much.

Sorry, I don`t know the reason.

I am using Maltab 2018b on Win 10, function `importdata(txt_file)` works on my computer.

>> f = importdata('tmp.txt')
f = 
  包含以下字段的 struct:

        data: [2×3 double]
    textdata: {'# a b c'}
>> f.data
ans =
     1     2     3
     5     6     7
>> f.textdata
ans =
  1×1 cell 数组
    {'# a b c'}

But I usually use another method to read txt file.

FileID = fopen('test.txt','r');
tline = fgetl(FileID);
count = 1;
content = {};
while ischar(tline)
	content{count,:} = tline; 
	tline = fgetl(FileID)
	count = count + 1;
end
fclose(FileID);

Also you can try to change from .txt to .csv, and use `csvread` to load data.

Thanks for the suggestion. I got the reason from the answer to 'Why does MATLAB crash on macOS Mojave 10.14.4 when I import data or open a file?'. It looks like I need to upgrade to a higher version.
