Image to Material (AI Powered) not working - stuck loading

Hello, I'm running into an issue with Image to Material (AI Powered). I open a new project, I click and drag my image into Sampler, and I select the appropriate Image to material (AI Powered) template.

My project is populated with the appropriate layers, but the Image to Material layer is stuck on this white/blue loading animation. The material is forever displayed as white. 

I am on Windows 11 Pro with an NVIDIA GeForce RTX 3080 graphics card. I have tried deleting the folder at ...\AppData\Roaming\Adobe\Adobe Substance 3D Sampler and relaunching Sampler, but that did not help.

I have also tried on a separate laptop, and encountered the same issue. I can't even open up older Sampler projects that use Image to Material, as they are stuck loading as well.

Attached is a log file. Any advice would be appreciated, thank you!
