Crash in iOS 15 Shortcuts

I’m reporting this exclusively because the latest update (released 6h ago) reports an “iOS15 ready” status. Otherwise, I’d have no expectation that this would work until GA.

Steps to reproduce:

1. Create a new Shortcut
2. Set as first step “Receive URLs input from Share Sheet (if there’s no input Continue)”
3. Set as second step “Execute shell command” with all default options:
- Open the app to execute the commands? default
- Keep going after an error: no
- Show When Run: yes
4. Add the first command: “python3 test.py Shortcut Input”

As soon as you try to exit the UI, for example by tapping on “My Shortcuts” or “Search for apps and actions”, Shortcuts will crash and the command at n4 will not be saved.

Variations of this flow produce the same result. For example, by assigning the “Shortcut Input” value to a custom variable “URL” via “Set Variable”, and then writing the command “python3 test.py URL” .

The crash happens both on iPhone and iPad updated to the latest iOS 15 beta.
