".... .asset cannot be opened...." after installation in MacOS

I just tried to installed Outsystems for my Macbook (Catalina v10.15.4) from the link below


During installation, it installed .Net framework for me. Once everything's done, every time I open Outsystems and at the end of loading a tones of error pop up shown as the following.

There are 20+ similar errors pop up in a row that involve a lot of different .asset files which seem to be in the same directory as the following:


I googled the solution but in vain. Any ideas what's going on?

Hi Stephan,

As macOS user guide suggests,

  1. In the Finder  on your Mac, locate the app you want to open.

    Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.

  2. Control-click the app icon, then choose Open from the shortcut menu.

  3. Click Open.

    The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.
