Checklist (we expect you to perform these steps before opening the issue)

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.
I have re-dumped the game and performed a clean install without mods and the issue is still present.
I have disabled all patches and cheats and the issue is still present.
I have all the required system modules installed.

Describe the Bug

The emulator crashes after hitting a Device lost during waiting for a frame assert after rendering any 3D scene in Rock Band 4, when using any NVIDIA graphics card. The issue appears on the released shadPS4 0.12.0 as well as the latest commit, across both Windows and Linux. AMD is not affected.

Speculation: I believe it's related to compute shader 0x4b5d4f31 (part of tiledlightsapplication.hlsl_ps4ps4 in the game files) - skipping over this shader avoids the crash entirely at the expense of completely broken lighting and texture mapping. The crashing doesn't affect version 1.00 of the game where the shader is completely different (0xc95b6a0f).

(also affects CUSA02084)

Reproduction Steps

Launch Rock Band 4 (version 02.21) on a Windows or Linux system with an NVIDIA GPU.
Wait through the introduction screens.
Assertion Failed! Device lost during waiting for a frame after the 3D scene starts to fade in.

Can confirm this also occurs on EndeavourOS Linux with an AMD Ryzen 7 5800X CPU and Intel Arc A380 GPU (with i915 kernel driver and Mesa's ANV Vulkan driver). The error message given by shadPS4 is slightly different ("Device lost during submit" instead of "Device lost during waiting for a frame"), but it crashes at the same point in the game. I can also confirm that it works just fine on my AMD card.

Interestingly, when the crash happened, a debug log from the ANV driver itself was printed in the terminal (though not logged in the above file). I'm unsure whether or not this is useful for debugging, but here's the output of that:

Not sure if this helps but I managed to use the CrashDiagnosticLayer by LunarG to get some information about whats going on during the crash.

This crash also happens while using Mesa's NVK driver, it seems like AMD gpus are the only ones not affected by this.
