QGC cannot write on PX4 microsd

Hi, I’m trying to upload a mission on the pixhawk 4 microsd, however, there’s a mission error stating that “Cannot write on microsd”
Any reason why this could happen? Really lost since I didn’t change anything, everything is fresh out of the box.
Below is the specific error log.

FYI: This error is from the vehicle firmware side. QGC is not trying to write to anywhere.
