As I try to read a database i created using ros2 bag in my linux vm using the point msg type. I always get this error:
'C:\code\TestRos2Bag\rosbag2_2021_04_20-06_32_06\rosbag2_2021_04_20-06_32_06.db3'.
Ensure that MATLAB has read/write permissions for the folder, the YAML file is
correctly formatted, and the bag file is not corrupted.
I checked all the file attributes and I have every permission needed. And the YAML file is also correct.The bag could be corrupted as it sais but i dont think so because i tried so many different bags and this one was even created by using a matlab publisher with a point msg and the recording it in the linux vm.

You have to use ros dashing to create the ros bag. For me it didnt work because i used eloquent probably because it is to old.
