Error using the VideoReader Function in Pop OS 20.04

I use MATLAB on Pop OS 20.04. I'm trying to read video files in a folder with .h264 extenstion (recorded with a Raspberry Pi camera) using the VideoReader function. The code I'm using is given below.

master=pwd;

VidFiles = dir('*image*.h264');

numfiles = length(VidFiles);

for i=1:numfiles

baseFileName = VidFiles(i).name;

Abs_baseFileName= fullfile(master, baseFileName);

v = VideoReader(Abs_baseFileName);

video = v.read();

end

It was working fine, but one day( I guess after a system update) it started giving me the following error:

Error using VideoReader/initReader (line 734)

Could not read file due to an unexpected error. Reason: Unable to initialize the video properties

Error in audiovideo.internal.IVideoReader (line 136)

initReader(obj, fileName, currentTime);

Error in VideoReader (line 104)

[e-mail](varargin{:});

How do I solve the problem?

This is a known issue, and is fixed in R2020b

As a workaround, you can set aside the libstdc++.so.6 file that ships with MATLAB. This might require root privilege.

For example, if MATLAB is installed at /usr/local/MATLAB/R2019b, you can open a shell and execute:

# cd /usr/local/MATLAB/R2019b

# cd sys/os/glnxa64

# mkdir unused

# mv libstdc++.so.6* unused/

MATLAB is tested with the libstdc++.so.6 that accompanies MATLAB. While unlikely, MATLAB might encounter unexpected behavior from your local version of libstdc++.so.6. If this occurs, try restoring the libstdc++.so.6 that accompanies MATLAB:

# cd /usr/local/MATLAB/R2019b

# cd sys/os/glnxa64

# mv unused/libstdc++.so.6* .

While this solution works, I get the same issue in 2020b
