Describe the bug
The latest IDE release does not work for me on macOS. The IDE will not pass the splash screen, and the splash screen will remain in the foreground until the application is quit.

To Reproduce
Steps to reproduce the behavior:

1. Drag Arduino IDE application off DMG and into the Applications folder.
2. Open the application in the Applications folder.

Expected behavior
The Arduino IDE starts and presents the workspace.

Screenshots

Desktop (please complete the following information):

• OS: macOS Big Sur 11.2.3
• Version: 2.0.0-beta.4

Additional context
I have been working on my own application using the Theia framework on the same computer, and I have not had any issues. I have never used Arduino IDE 2.0 on this computer before. I have the traditional IDE installed and working.
