Cursor 1.4.4 keeps Crashing

Describe the Bug

I am working on a large project and am experiencing a problem where a request to Chat GPT5 keeps crashing. A window pops up saying that the cursor is not responding, and I can then restart it. I have already tried a completely new chat. It keeps happening. What can I do? The cursor becomes very sluggish and no longer responds. Is this a known issue? And when will there be an update?

Steps to Reproduce

I think you can only reproduce it in an large Project with much files and much changes in much files. In my Case there are many JSON Schemas which ChatGPT5 changed and now it is in the bugfixing Process because a lot of tests are failing.

Operating System

Linux

Does this stop you from using Cursor

Yes - Cursor is unusable

It seems this happens when the LLM (in this case GPT-5) calls a lot of shell commands with very much output. I now instructed the LLM to write the debug output to a file an grep for specific parts in this file. It looks like now Cursor is not crashing any more. In my case i have a lot of tests ..and when all tests are running this produces a lot of output in the shell.

What do you mean “specific parts” - Do you have a rule you can share that works?

I simply wrote in my request text in the agent chat that it causes problems when the entire output is processed directly by “him” … i.e., instead of redirect everything to standard output, “he” should first redirect the output of a vitest run completely to a file, and then “he” should only grep for the output that is of interest to him. Chat GPT-5 uses a lot of shell tools anyway, as I have seen. Hope this was understandable to you. Im Working on Linux.. so there are a lot of Text File Manipulations are possible for the LLM.
