I don’t know to be honest, latest

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. Which model are you using? Does this also happen in new chats?

Ryan_George · September 8, 2025, 4:05pm

I’m also getting this error, popped up since last night, seems like a force install of a buggy update.

deanrie · September 8, 2025, 4:08pm

Hey, thanks for the info. Could you please specify which version of Cursor you’re using, which model, and if you’ve tried this in the new chat?

stevekarwacki · September 27, 2025, 8:35pm

I am experiencing this issue with Cursor version 1.6.45 while using the Claude-4-Sonnet model. Starting a new chat with a different model and going back to my erroring chat does NOT correct the issue. I fear that context window is completely dead which means I lost hours of work this morning.

deanrie · September 28, 2025, 9:55am

Are you using any MCP servers? Please try disabling them and check if the error still occurs.

stevekarwacki · October 9, 2025, 12:16am

I was not and never have used a MCP server

ignacio_ferreira · October 18, 2025, 7:18am

Hello, no, not using any MCP server.

ignacio_ferreira · October 18, 2025, 7:19am

Issue happens still from time to time but less frequent I think-

deanrie · October 18, 2025, 9:53am

Hey, which version of Cursor are you using?
