Use google collab or try to install it without the GUI. This GUI is good but the default and only option of "half precision" makes it impossible to generate images in some nvidia graphic cards (GTX 1650, 1660, including SUPER) it happened to me, the solution was installing the code locally without any GUI, there are some websites that explain it:
How to Run Stable Diffusion Locally to Generate Images (assemblyai.com)
or you can watch some youtube videos too .
Once you have it running, in the terminal use the command --precision full. That should solve the issue it did it for me! good luck out there and wait for the new version of this GUI this is just the 0.1v
