Minecraft Launcher for mac is a blank screen

I downloaded Minecraft like a month ago and it worked just fine, but when I tried to open the Minecraft launcher yesterday, it was just a blank gray screen. No warning message. I tried to reinstall Minecraft, and I tried to remove the launcher folder under ~/Library/Application Support/minecraft to restart the update, but none of them worked. I added a screenshot and the launcher log to the attachments. Please let me know how I can fix it.
