See what this reveals:
type('C:\Users\erand\Downloads\T1.mat')
It may just produce garbage, however it may also reveal the problem.

can you share the T1.mat'?

It failed forr me as well:
LD = load('T1.mat')
Error using load
Invalid field name: 's?????_label'.
The ‘?????’ may be Unicode characters or something else that MATLAB doesn’t recognise as acceptable. There doesn’t appear to be a way to modify load to import those, since you already tried '-ascii' and that obviously didn’t work.
See if you can find a valid version of the file. There’s nothing further to be done here.

The binary .mat file contains invalid variable names such as
---#_label 1x1 116 cell
----#_label 1x1 116 cell
------#_label 1x1 116 cell
-------#_label 1x1 116 cell
---------#_label 1x1 116 cell
----------#_label 1x1 116 cell
--------------#_label 1x1 116 cell
-------------_label 1x1 116 cell
------------_label 1x1 116 cell
---------_label 1x1 116 cell
---------_label 1x1 116 cell

----_label 1x1 116 cell
--_label 1x1 116 cell
--_label 1x1 116 cell
--_label 1x1 116 cell
--_label 1x1 116 cell

-_label 1x1 116 cell
-b---_label 1x1 116 cell
???-_label 1x1 116 cell
???_label 1x1 116 cell
Unfortunately on my Mac, a message is generated about "Warning: Too many duplicate names"

By the way, if you use
load T1.mat
without any output arguments then it will not give any warning or error, and will load all of the variables that have valid identifier names, skipping the entries that have invalid identifiers.
However, if you use
S = load('T1.mat')
or
S = load('-mat', 'T1.mat')
then it will fail, complaining about invalid variable names.
The FEX contribution, as-posted, is able to fix up some of the variable names, but not all. (I assume it could be modified to support more names.)
