Follow-up Comment #1:

Confirmed.
I think this may well be a duplicate of bug #52867, or is related to it. That
said, the old strread.m has this same bug here but worked for bug #52867.

It is the EOL that somehow confuses textscan.
A way to read your data is to change the EOLs into a delimiter first:

>> f_in = fopen('bug_example.txt');
>> txt  = fread (f_in, Inf, "*char")';
>> fclose(f_in);
>> txt2 = strrep (txt, "\n", ",");
>> values = textscan(txt2, '%f %f %f %f', 'Delimiter', ',')
values =
{
  [1,1] =
      1
      5
      9
     13
  [1,2] =
      2
      6
     10
     14
  [1,3] =
       3
       7
     NaN
      15
  [1,4] =
       4
       8
     NaN
      16
}
