Hi Rafael,
I tested creating a new project and TWR-K24F120M project, there is no problem, see attached two videos.
here is some points we need to pay attention:
1. make sure you have admin right of install and using KDS . it's necessary.
2. to avoid old file associations, remove .metadata folder under your workspace folder, then restart your project again. test same.
3. make sure you install the latest KDS version: KDS2.0

4. make sure you install all the available update:

does this answer your question?
Have a great day,
Zhang Jun
