Tried using rosbag in R2020b and its working fine. There may be some issue in the file or arguments you are passing into it. Check here for documentation.
Or if you can share some more details we can have a deeper look at it.

I have the same problem, see the following file...
I just call ' bag = rosbag(filename); ' and an error occurrs: "An error occurred when reading from the file."
I also tested bag files downloaded from internet and the problem is the same.

I have the same problem after Matlbab update.
I attached the file that works for me with R2020a but not with R2020b.
Thanks in advance for your time

I found a solution to the problem, it's very simple, file path of your bag cannot have Chinese character.
