**Error description**
I have Espressif IDE development tools installed since, espressif-ide-setup-3.0.0-with-esp-idf-5.2.2.
When I open Espressif IDE and create a project everything works fine with autocompletion (either when I try to include a header file or when I declare a structure type variable). Once you build the project for the first time, then the autocomplete stops working and never works again until you create a new esp-idf project. In the message in the attached image I get this error java.util.concurrent.CancellationException I have repeated the reinstallation many times and the problem is the same.


**Expected behavior**
I need autocomplete to work because it is an important help when programming. I need to know if there are any manual settings that have to be entered for it to work well.

Hi ivargas95 did you get this figured out? I'm having the same issue as you are.

Hello atouron, I have found a temporary solution.
Apparently project directory names in Espressif IDE cannot have whitespace. It could be a bug in that new version because in previous versions there is no such problem. Below are examples of routes with errors and examples of correct routes.

Error:
D:\Example SoC Esp32\ProjectsESP32
D:\Esp32\Projects ESP32

Correct:
D:\Example_SoC_Esp32\Proyectos_ESP32
D:\Esp32\ProjectsESP32
