If you were developing in Unity and suddenly the Quest Pro stopped hand tracking from the system men

I was developing an app using hand tracking with Unity and Quest Pro, but suddenly the hand tracking stopped working. Previously, it would seamlessly switch between controller and hand recognition, and I could use hand gestures. To resolve this issue, I tried restarting Unity, restarting the Quest Pro, reviewing the Quest Pro settings, and restarting my PC. However, the problem persisted. Finally, I decided to perform a factory reset on the Quest Pro to restore it to its original settings and set up the development environment again, including hand tracking and Quest Link. Unfortunately, the issue still wasn't resolved. I also made sure to update the software. After that, I didn't touch it for a day and a half.

When I touched it again, I found that I could use hand tracking from the system menu, and even in the Unity app.

Has anyone else experienced similar symptoms? Or could this be a bug with the Quest Pro? It's quite concerning because I need to demonstrate the app to clients for work, and suddenly losing hand tracking capability is very worrying.

I would greatly appreciate it if someone could shed light on the cause of the hand tracking issue and provide immediate solutions. Thank you in advance.
