The _sharedTrashURL generated with [[NSProcessInfo processInfo] globallyUniqueString]; contains %00%00%00%00 , lead to a crash.

Device: iPhone Xr
iOS 14.2 (18B92)

Nope. It was finded in my crash collector, but I never reproduce this case.

@Jason-Stan-Lee is it something you're seeing occur a lot? Is there any particular version of iOS it occurs on?

@garrettmoon There are very few crashes, perhaps one over a million or a billion, the platforms which crashed are in following

iPhone Xr | 12.3 (16F156)
iPhone 11 Pro Max | 13.3.1 (17D50)
iPhone Xr | 13.1.3 (17A878)

I guess the globallyUniqueString is not very suitable for url path.
