sending USDT erc20 tokens from Trezor wallet to exchange

Hello, I have been a Trezor wallet user for about 4 years, during which time I received and sent various tokens many times. Since yesterday, I have been trying to send USDT tokens from my Trezor wallet to the exchange on the ERC20 network. Naturally, I have eth on my balance, I set the gas in different ways, recommended by the wallet and maximum for fast sending. I tried 4 times and all 4 transactions hang unconfirmed. Can you please tell me what to do?

You have to cancel the oldest stuck transaction, sending new ones will not work they just keep getting queued.
