Cursor times out loading current chat and opens new chat that lacks context

I have Cursor v0.49.6 running on a Macbook Pro M3 with MacOS 15.4.1 (Sequoia). I have been using Cursor for implementing a relatively complex Agentic AI application. I have found that every 2 days or so, occasionally when I return from a break of a few hours, Cursor does not proceed where it left off, but keeps showing “Generating…” for a while and eventally times out saying “Try Again”. Even if I type Cmd-Shift-P, enter “Show Chat History” in the palette and select the chat I want to load, it times out and opens a brand new chat instead which does not have the the rich context of the current chat I’m trying to load. For example, in the screenshot that I uploaded, I would like to upload the chat “Status Update Inquiry”, but it times out and opens a new chat instead. How can I load my current chat reliably? Thanks and appreciated!
