    I have found the cause of the freeze.

    Based on my tests, I discovered that the freeze occurs when there is high memory usage, and continuously allocating and deallocating memory leads to the freeze. By reducing our application's memory usage, I found that the issue could no longer be reproduced.

    Previously, our PSS was around 3.7GB. We managed to reduce it to 2.5GB through various means, and after 200 cycles of repeated openings, there were no freezes. Before, it would freeze after about 20-30 cycles.

    I hope this can help future developers.

I tried using OpenGLES3, but it seems that OpenGLES3 has depth precision issues on the Quest 2, causing severe z-fighting, so we cannot switch to OpenGLES3.

I have upgraded Unity to 2022.3.31f1, upgraded the Meta SDK from v62 to v65, and also updated the Oculus XR Plugin to the latest version.

Based on user feedback and our testing, the freezing issue still persists. However, we found that it is possible to force shut down by holding the power button for 30 seconds. Users who said they couldn't shut down might not be aware that they can hold the power button for 30 seconds.

Additionally, based on our testing, we found that we can relatively consistently reproduce the issue by repeatedly calling multiple ParticleSystem.Play methods. However, this hasn't helped us find the root cause.
