What it means
A transaction that reverts with the raw data 0x675cae38 hit the custom error InsufficientToken, defined in Uniswap Universal Router. The explorer shows the hex because it does not have the contract's ABI to translate it.
The router ended a step with fewer tokens than the next step needed, typically a fee-on-transfer token shrinking mid-route.
How to fix it
Use the fee-on-transfer supporting route if the dapp offers one, or trade the token on a venue built for its transfer fee.
