Severity:
Arbitrum does not yet support `PUSH0` opcodes used by Solc compiler version 0.8.20, deployment to Arbitrum will fail
Summary
Solc compiler version 0.8.20 switches the default target EVM version to Shanghai, which means that the generated bytecode will include PUSH0 opcodes. Arbitrum does not yet support PUSH0 and, hence, deployment to Arbitrum will fail.

Recommendations
Either
use solc compiler version 0.8.19 (or earlier), or
wait for Arbitrum to add support for the EVM Shanghai upgrade and the
PUSH0opcode. The proposal to add such a support has recently passed, and the changes are expected to take effect on 2024-01-27.
