I need your context: what environment you’re using, which version, and how you’re running it. Otherwise, I can’t reproduce your issue or help you fix it.

1. For me, the most convenient option was Pinokio (Ace Step UI, which contains Gradio and works through it) because there are no “complications” with installing accelerators, tritones, virtual environments, etc. All functions in the Pinokio version work properly with any models and in any scenarios. I just use Gradio from "Step UI" without a custom “skin.”

2. When the “LRC” problem popped up, I tried installing it manually and directly from your GitHub page (portable build and regular), but the problem is still there. (The problem started around the 10th-16th of this month.)
   Everything works except LRC

3. I use the Pinokio version because there are no problems with manual installing Flash Attention and Triton. A convenient one-click solution.

IN SHORT: Everything worked before, but stopped after one of the latest updates. The console does not contain any errors and allows you to use any combination of generation models and LLM.

I tried different options for auto-start and manual start.
Windows 11x64
Python 3.12 and 3.11 (I tried them separately in different combinations with different options - through Pinokio, your manual instalation and portable option)
3090 24GB (latest driver)
Edge browser and FireFox (latest vers)
latest version every time i run it.

[kajan988]

What else do you need from me to understand the problem?

[ChuxiJ]

I'm not sure which version of your code you're using.

That's it. I figured it out.
LRC works when “Think”=off.

Is that how it's supposed to be?
Did it always work like that before?
