Is there a problem with Topaz Gigapixel generative upscaling today?

I’ve been attempting to upscale an image today on my Windows 11 PC, and so far I’m only able to use Firefly or Topaz Bloom, but I need to be able to use Topaz Gigapixel. Normally this is a very fast process for me, but today the progress bar spends several minutes gradually filling up, and if I let it continue it was eventually giving me an error although the last couple of times I tried the progress bar went away and I didn’t see the error. I’ve never experienced this until today, and I’ve tried the option on two different machines unsuccessfully.
