MacOS 12.4: Safari won't open new window
Over the past two weeks, I've been unable to open a new window in Safari. When I open the application, I see the dot under the icon and the menu text but no window. If I click Bookmarks > Show Start Page, the window opens but is completely grey without any content. Safari also won't open in Safe Mode.
System Info:
Macbook Pro, 13in, 2020
MacOS 12.4
Safari 15.5
Attempted troubleshooting steps:
Boot into recovery mode and perform first aid on all volumes
Open in Safe Mode
Clear cache, *.plist, and settings files
Confirm network settings
Turn off Safari extensions
Install all OS and App updates
It appears that my Safari is somehow corrupt. It is not feasible for me to reinstall MacOS, and cannot find another way to reinstall Safari. Any suggestions?
