OpenZeppelin 5
error InvalidInitialization()A transaction that reverts with the raw data 0xf92ee8a9 hit the custom error InvalidInitialization, defined in OpenZeppelin 5. The explorer shows the hex because it does not have the contract's ABI to translate it.
An upgradeable contract's initializer was called when it must not be, for example a second time. A deployment or upgrade-time error, not a user one.
Nothing user-side. If you are deploying, review the initializer flow.
