I think it happens because of ‘Index Repositories for Instant Grep(BETA)’. At first, I turned off ‘Index New Folder’ since it looked like all about indexing as you told me. But It didn’t work. So I turn off that beta function. And It works! It’s beta and I think It should be turned off at first after installing and launching Cursor IDE If a project is big. When a project is small, It still works on the project(small one).
Cursor IDE doesn’t work on the proejct(files 4,189 / folder 722 / storage 1.4GB)
Cursor IDE works on the project(files 786 /folder 288 / storage 233MB)
I hope It will gonna help someone.
