Codebase search not working

Bellow is my cursor version info:

Version: 0.42.5
VSCode Version: 1.93.1

V8: 12.4.254.20-electron.0
OS: Darwin arm64 24.1.0

My feeling is before Version: 0.42.5, the codebase search is working, but after this version, not work at all.
Is there anyway I could get back to older version.
codebase search is the primary reason I paid for cursor pro.
even the composer may accidentally edit other files with codebase index, but it is ok for me, for I could use git diff to review its change.
