I tried with iPhone SE, Prod mainnet, 2.6.0, iOS 14.0.1:

1. Clean app install
2. Click load safe button on main screen
3. Tab "scan qr code"
4. Actually scan QR code (https://etherscan.io/address/0xFB1d445c27A860bb6330453Bf08254198F3E0E31)
   -> Address is not filled
5. Scan again (https://etherscan.io/address/0xFB1d445c27A860bb6330453Bf08254198F3E0E31)
   -> Address is filled
6. Next
7. enter name
8. Finish adding Safe
9. go to safe settings
10. Delete Safe
    -> No crash

In the 2.7.0 I am not able to create duplicated safes. If a few duplicated safes were created in the 2.6.0 it can be deleted without the crash in the 2.7.0
app version 2.7.0 (229)
