Fresh install on MacOS 10.15.4 - Won't start :(

Hi all!
As I couldn’t update my Atom anymore (don’t know why), I decided to uninstall it and install a fresh version of the latest Atom.
Installed by moving the Atom icon in the Application folder, and then started by double clicking this icon.
Atom ask me for permission, but even giving permission to it, it stops loading and shut down.

I’m on Catalina 10.15.4, which is the latest version of macos at 26 march 2020.

Thank you for your time and your help :slightly_smiling_face:
