Issue with VK_KHR_timeline_semaphore

When using VK_KHR_timeline_semaphore, vkCreateSemaphore returns -3 with the following in logcat:

 

<gsl_ldd_control:556>: ioctl fd 68 code 0xc0100958 (IOCTL_KGSL_TIMELINE_CREATE) failed: errno 13 Permission denied

 

As mentioned in the error, permission is denied, further logcat analysis indicates that the OS is preventing access to /dev/kgsl-3d0. It's also worth noting I run a Meta Quest 2 on the latest publicly available firmware.
