[Bug] Tomodachi Life: Living the Dream keep crashing mid-session with DescriptorSetUpdater IndexOutOfRangeException

[oliveripkanam]

Prerequisites

• I am confident that my issue has not been reported already in open OR closed issues.
• I am able to reliably reproduce the issue on the latest stable or canary version.
• I am not using an unofficial build (Flatpak, Emudeck, etc.).
• I am a silly goose and didn't read these boxes.
• I am a silly goose and DID read these boxes.

Description of the issue

The game runs fine for 20-30 minutes then crashes with this error:

|E| GUI.RenderThread Application : Unhandled exception caught: System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at Ryujinx.Graphics.Vulkan.DescriptorSetUpdater.SetUniformBuffers(CommandBuffer commandBuffer, ReadOnlySpan`1 buffers) in DescriptorSetUpdater.cs:line 634
   at Ryujinx.Graphics.GAL.Multithreading.CommandHelper.<>c.b__5_1[T](Span`1 memory, ThreadedRenderer threaded, IRenderer renderer) in CommandHelper.cs:line 43
   at Ryujinx.Graphics.GAL.Multithreading.ThreadedRenderer.RenderLoop() in ThreadedRenderer.cs:line 146

Reproduction steps

• Happens at both 2x and 3x resolution
• The GPU "too slow" warning appears in the log shortly before the crash
• Setting Backend Threading to On seems to make it crash faster than Auto
• This is a separate crash from the fountain crash already reported in issue [Bug] Tomodahi Life: Living the Dream - Crashes on Wishing Fountain and Photo Shop #379
