The compiler for Solidity 0.8.20 switches the default target EVM version to [Shanghai](https://blog.soliditylang.org/2023/05/10/solidity-0.8.20-release-announcement/#important-note), which includes the new `PUSH0` op code. The compiler for Solidity [0.8.20+](https://github.com/ethereum/solidity/releases) did not remove the `PUSH0` op code. This op code may not yet be implemented on all L2s, so deployment on these chains will fail. To work around this issue, use an earlier [EVM](https://docs.soliditylang.org/en/v0.8.20/using-the-compiler.html?ref=zaryabs.com#setting-the-evm-version-to-target) [version](https://book.getfoundry.sh/reference/config/solidity-compiler#evm_version).
