I have a similar issue. Did you ever find a solution to your issue?

I need to use Designed for iPad until certain third-party frameworks are updated to support visionOS. I would like to make the background of the app semi-transparent (low alpha) to reveal the surroundings behind the app. The best I can get is a black background, even with a clear window and view. Is there a way to make whatever is behind the window (the UIScreen?) clear as well?

Rebooting worked for me.

It's back. Same errors. Tried all the previous fixes - no joy.

I'm seeing these crashes also, but only for Beirut (!). You can recreate by setting the device's time zone to Beirut, while leaving the current Region to United States (or any region other than Lebanon). Force current Region to Lebanon in Edit Scheme - Options - App Region and it doesn't crash. But setting the picker's locale to en_LB (Lebanon) doesn't help. There must be something specific about the mismatch of time zone and region for Lebanon but I haven't found it. A (poor) workaround might be to identify the mismatch and switch the picker.preferredDatePickerStyle to .wheel in that case only.

I've implemented @commanderk's approach and while it is does work, it's not the robust solution that an API would provide. So: 1) @eskimo - anything you can tell us on when to expect an API solution (even "soon" or "not soon" would help). 2) @commanderk - any improvements since your post 3 weeks ago?
