I have agreed to the Xcode license (via the command line). I don't know why, but I can't open Xcode. When I try, it crashes immediately. I did download the Tahoe intel version from the Developer site, but Xcode still won't open.

In particular, I can see from the verbose output that 'make' was working during those builds. Now, 'make' gives the error, even after trying to reinstall the command line tools (the dialog pop-up offers to install them, and I click the button to do it). 

Ok, the other suggestion I found was to delete /Library/Developer/PrivateFrameworks/CoreDevice.framework

However, I also found that removing this framework might prevent you from using the Xcode simulator, if that's important to you.

I also found that if you need that framework back, you can reinstall it with:

open /Applications/Xcode.app/Contents/Resources/Packages/XcodeSystemResources.pkg
