What it means
A transaction that reverts with the raw data 0x8dfc202b hit the custom error ExpectedPause, defined in OpenZeppelin 5. The explorer shows the hex because it does not have the contract's ABI to translate it.
The opposite gate: a function that may only run WHILE paused was called with the contract unpaused. An operator-side error.
How to fix it
Nothing for a regular user to do. If you operate the contract, pause it first.
