"Automatic1111 is Offline" and Various Other Errors

I installed the Auto.Photoshop.SD.plugin_v1.2.5.ccx plugin on my PC, but I'm encountering several errors. I'll list the errors I'm experiencing, and I would really like to resolve them.

Before we proceed, I believe it's important to mention that I don't have Python installed. Could that be the issue?

Errors:
1 - "Automatic1111 is Offline: make sure Automatic1111 is running in the background, or select the 'native horde' option from the horde tab."

2 - Another error message I encountered is: "Auto Photoshop Stable Diffusion Plugin: The 'Show' command is not currently available."

3 - When I go to "Horde" and enable "Native horde," I get a different error from the first one. Here it is: "Due to heavy demand, for requests over 938x938 or over 50 steps (25 for k_heun and k_dpm_2*), and for 12 or more weights, the client needs to already have the required kudos. This request requires 0.0 kudos to fulfill."

I'm using Windows 10 and have the latest version of Photoshop installed.

I also encountered issues with Google Colab for Automatic1111, where it would close after just a few seconds. I tried using it with Photoshop, and now I'm facing different problems.

Thank you so much for taking the time to read my message. I would be extremely grateful to anyone who can assist me with this issue
