    i have tried in two computer with 2080 and 3060ti ,both of them has the same problem.
    and 2022lts crash about ten times in one day.

    in the profiler
    this function Gfx.WaitForPresentOnGfxThread() use about 50ms in a tick.
    in 2021LTS every thing is ok.

    I noticed a decrease in performance on Android even without using RenderTexture. In my project, FPS dropped from 60 to 35. The bug report was sent. IN-49712.

    Quick check:
    In 2022 make sure soft shadow quality is at low if you use it. 2021 always has low on soft shadows, 2022 it defaults to medium
