Error: "Unable to read some of the variables due to unknown MAT-file error."

Hello, I have a 3.1 MB .mat file that contains activations from a hierarchical model, after reading a set of 504 images in double format. When I try to read the file in MATLAB, I receive the following error:
"Warning: Unable to read some of the variables due to unknown MAT-file error.
> In matfinfo (line 9)
In finfo (line 118)
In uiimport/gatherFilePreviewData (line 414)
In uiimport (line 244)
Error using load
Number of columns on line 2 of ASCII file
/Users/hsnsplazaresearch/Analysis/hmaxMatlab/output/exampleActivations.mat must be the same as previous lines.
Error in uiimport/runImportdata (line 465)
datastruct = load('-ascii', fileAbsolutePath);
Error in uiimport/gatherFilePreviewData (line 433)
[datastruct, textDelimiter, headerLines]= runImportdata(fileAbsolutePath, type);
Error in uiimport (line 244)
gatherFilePreviewData(fileAbsolutePath);"
I am highly confused, because the data is not ASCII. When I open in a text edtior (Atom), it appears like so:
"^[w<��H��UJT����r*IVQ��_TdDd�JJ!
�d�yp�=�=�풒�}�?�g|����ݓm�{�?��#���x7,^�"
The function was adapted from the HMAX model for machine vision, and the tarball can be found here: https://maxlab.neuro.georgetown.edu/hmax.html#code
The version is 2019a. Thank you so much for your time.

When I drag-drop the first mat file into my workspace,
Error using load
Unable to read MAT-file C:\Users\name\Documents\MATLAB\exampleActivations.mat.
File might be corrupt.
When I load that file with the import tool
Error using load
Number of columns on line 2 of ASCII file C:\Users\name\Documents\MATLAB\exampleActivations.mat
must be the same as previous lines.
Error in uiimport/runImportdata (line 465)
datastruct = load('-ascii', fileAbsolutePath);
Error in uiimport/gatherFilePreviewData (line 433)
[datastruct, textDelimiter, headerLines]= runImportdata(fileAbsolutePath, type);
Error in uiimport (line 244)
gatherFilePreviewData(fileAbsolutePath);

Hi Will Q,
I can load 2nd (exampleActivations2) mat file data
%
load_mat = load('exampleActivations2.mat')
load_mat =
bestBands: {1x8 cell}
bestLocations: {1x8 cell}
c2: {1x8 cell}
extract_data = h.c2{1};
imshow(extract_data)
%

But while loading 1'st mat file. I got error as like file may be corupted.

Error using load
Unable to read MAT-file E:\Sample MATLAB Program\MATLAB_Cent\exampleActivations.mat
File may be corrupt.
If possible to recreate a mat again.
