Gfx.PresentFrame caused huge stutter

Unity Engine

Sometimes Gfx.PresentFrame causes huge stutters, getting stuck for about 8 to 10 seconds.
This is a relatively difficult problem to reproduce. Sometimes it occurs within a few minutes, and sometimes it does not occur for more than ten minutes. I have not found a stable method to reproduce it.

Has anyone had a similar problem, or know what could be causing this? Or is this a Unity bug?
Thank you in advance!

I have the same problem as you, repeated on HUAWEI HONOR V30, OS: HarmonyOS 2.0.0, CPU: Huawei Kirin 990.
Did you got any solutions?
