Hello.

Create a normal EC2 instance and try mounting the EBS volume that is experiencing the problem using the steps described below.  
It should be possible to copy the necessary files and data after mounting.

1- Stop the instance then Detach the EBS Volume

2- Create new instance then Attach Volume (the one which has been detached)

3- SSH into the new instance and mount the volume

4- Change default root

6- Stop Rescue Instance then detach then attach back to Server then Start Instance and 3 Status Checks will Passed
