error ERC20InvalidSpender(address)A transaction that reverts with the raw data 0x94280d62 hit the custom error ERC20InvalidSpender, defined in OpenZeppelin 5. The explorer shows the hex because it does not have the contract's ABI to translate it.
An approval names an invalid spender, typically the zero address.
Rebuild the approval from the dapp. If it recurs, the dapp is producing a bad spender address.
