AI keeps not-responding, hanging

AI hangs regularly and fails to respond. About 5-8 hours into a campaign. I cleared out the context window recently, but the AI keeps hanging / lagging. When it lags out, takes maybe 60 seconds to even tell you it failed, very annoying. It provides no input on why it’s failing. If it logged something, “I couldn’t find a character.” or something like that as to why it failed, maybe the user could fix it. But as it stands, it just hangs for unknown reasons.

I try changing my response, and it generally keeps happening. After changing my response 4-5 times, sometimes I can trigger it to progress forward.
