Tether (USDT) on TRC20 Tron Appears Blocked in My Trust Wallet

I use Trust Wallet to hold my Tether (USDT) on the TRC20/Tron network. On 30 September 2025, I realised that approximately 100 USDT in my wallet appeared to be blocked, and I have not been able to use or move these tokens since then. I did not make any transaction immediately before noticing this situation, so I cannot understand why the tokens are blocked. Until now, I have not contacted either Trust Wallet or Tether support about this issue. Through this complaint, I would like my Tether tokens on the TRC20/Tron network held in Trust Wallet to be unblocked as soon as possible so that I can access and use my funds again, or I would like to receive a clear explanation and solution for this situation.
