error ERC20InvalidSender(address)A transaction that reverts with the raw data 0x96c6fd1e hit the custom error ERC20InvalidSender, defined in OpenZeppelin 5. The explorer shows the hex because it does not have the contract's ABI to translate it.
The token transfer names an invalid sender, typically the zero address, which the standard forbids.
Almost always a contract-side bug in whatever built the transaction. Report it to the dapp.
