I cannot install any widgets on my simulator, even the system provided ones. I just finished removing all dev software from my machine and reinstalling only Xcode 16.3. Springboard always crashes:

So it's crashing when it tries to make the little animation when a widget is dropped. I removed all the runtimes, every cache and preference I could find, emptied the trash, rebooted (to release any open file descriptors), and reinstalled Xcode. Nothing helped.
