Gigapixel AI 6.22 Processing errors on RTX 4090 (nvidia drivers: 526.98)

I’ve been using Gigapixel for a while now. After replacing my 3x RTX 3090 GPUs with 2x RTX 4090 GPUs, I keep getting this error.

I’ve updated my GPU drivers (clean uninstall with Display Driver Uninstaller) and I’ve tried changing the preferences to see if it would work with just 1 GPU, and it gave me the same error.

I’ve also uninstalled Gigapixel and reinstalled with the latest setup file and I’m still getting the same error message.

As of right now, the only way to correctly make Gigapixel work is to resort to CPU upscaling. But considering that I have the most powerful GPU on the market with many CUDA cores to spare, I was hoping I could get some help with this.
