Windows 11: Fatal Error: Case Sensitive File System

I am working on a Unity project (this one specifically) on Windows 11. It takes human pose data from a .csv file and animates an avatar.

1] This was working fine until once when it suddenly stopped working (i.e. the project opens but the avatar stays still instead of performing the movements)

2] When opening the project, I saw the following error:

Fatal Error! The project is on case sensitive file system. Case sensitive file systems are not supported at the moment. Please move the project folder to a case insensitive file system.

I wanted to know whether issue 1] could be because of error 2]. Since the project involves reading from files. Note that the project does open in Unity (though the animations don't work) inspite of the error.

See below file system info of the disk in which the project is stored:
