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

Knack gives a device lost error when loading on NVIDIA.
With CrashDiagnostic enabled, it looks like a shader is trying to return a negative value.
And for whatever reason this negative value error doesn't show up in shad_log.txt.

Reproduction Steps

Run KNACK on a NVIDIA card

Specify OS Version

Windows 11 24H2

CPU

Intel Core i7-10700F

GPU

RTX 2060 SUPER

Amount of RAM in GB

32GB

Amount of VRAM in GB

8GB

Log File

shad_log.txt (debug log filter enabled, for whatever reason it will not boot at all without debug filter on.)
Crash diagnostic dump (renamed to text file from YAML): cdl_dump.txt

shad_log.txt
cdl_dump.txt
these are the actual problems, the negative value error is really just another device lost error.
