ISSUE
I can no longer access to Steam Mobile App. It crashes every time I open it.

OS
PC: Windows 11
Phone: iOS

STEPS
1) Switch Steam Client to Steam Families Beta
2) Create a Family
3) Delete the Family
4) Restore the Family you deleted
5) Delete the Family again

RESULTS
- Steam Mobile App no longer works, crashes after showing Steam logo when opened.
- A red "Failed to load the family data. You do not have permission to perform this action." error on Manage tab of Family Management.
- "Something went wrong while displaying this content. Refresh
Error Reference: Store_8808118_2284e030371fb2a7
Cannot destructure property 'settings' of '(0 , p.X1)(...).data' as it is undefined." error on Library tab of Family Management.
- Notifications are broken.
On stable Steam client and browser, notifications button shows what notifications I have and when I press "View All", it shows 0 notification.
On Steam Families Beta client however, both notification button and notifications page you open when you press "View All" shows 0 notification.

EXPECTED
- Steam Mobile App should work.
- Family should be deleted as normal.

ADDITIONAL INFORMATION
- I'm using Steam Families Beta client.
- Switching back to stable Steam client didn't fix anything, Steam Mobile still crashes.

- Both PC and Phone operating system is up-to-date, internet is connected with no issues, meets requirements and Steam Mobile App is up-to-date.
