mta.yaml stuck in "Loading"

[matmir]

Hi!

I've created a "new proyect from template", using the CAP Project template.

After creation is done, while trying to open the "mta.yaml" file, in order to make some configurations, there is no content, and the screen is showing the word 'Loading' (this state will never change, it's stucked):

Thank you!
