USDT transfer freezes and wallet recovery issue on iOS 16.7.12 (App v0.45.2)

Description

Hello Unstoppable team,

I'm currently using Unstoppable Wallet on iOS 16.7.12, App version 0.45.2.

1. Transfer issue:
   In this version, the app freezes and crashes immediately after I input an amount and attempt to send USDT on any network (TRON, Polygon, etc.).
   The screen becomes unresponsive for a few seconds and then the app force-closes.

2. Wallet recovery issue:
   I created my wallet in the first half of 2025 on iOS.
   When I try to recover it using my 12-word recovery phrase, the restored wallet shows no USDT balance and does not load my original TRON address.
   I have confirmed on Tronscan that my TRON USDT balance still exists at my original address, but I cannot reproduce this address from my recovery phrase.
   It seems the derivation path for TRON wallets in this version might be different from the standard paths (e.g. m/44'/195'/0'/0/0 or m/44'/60'/0'/0/0).

Could you please confirm:

• The correct derivation path used for TRON (USDT-TRC20) wallets in iOS App v0.45.2?
• And whether the USDT transfer freeze/crash issue is a known bug in this version?

Device Info

• iOS version: 16.7.12
