IntelliJ Ultimate, stopped recognizing index.ts files no code completion

HI, for some reason it has stopped showing me code completions in all of the index.ts files in my project, although the project is compiling, even the code completion in other project file is not showing the paths exported from index.ts files, I don't know how does this happen but I really need help in this. Reinstalled the Ultimate almost three times :/ nothing changes

thanks
