VideoReader is unable to read properties and frames

Hi everyone,
I have been using VideoReader() for a while, but have run into some issues after updating to Ubuntu 20.04. It seems that it isn't able to load any of the video properties, or the frames, anymore.
Reading a file with:
vid = VideoReader('The_Present.mp4');
I just get something like this:
General Properties:
Name: 'The_Present.mp4'
Path: '/media/max/RedPassport/ECoGData/Tobii/video_files'
Duration: 258.6010
CurrentTime: 258.6010
NumFrames: 0
Video Properties:
Width: 0
Height: 0
FrameRate: 0
BitsPerPixel: 0
VideoFormat: ''
Reading a frame with
readFrame(vid)
results in
'No more frames available to read from file.'
When I loaded the same file on Ubuntu 18.04 I had no issues.
I suspect it is some issue with reading the codec. However, changing the codes on the movie file isn't an option as I need to preserve the information as is.
I tried to update gstreamer, but that didn't help.
I would apprechiate any help on this!

I'm also having this problem with R2021a Update 4 / Windows 10. But sometimes it works.
It's frustrating.

Updating Matlab from 2020a to 2020b solved this issue.
