It returns: invalid opcode: opcode PUSH0

I am assuming you're using Solidity version 0.8.20. What happened is in the new solidity, Ethereum is the only blockchain that supports the 0x5f op code. That's why your code works on Goerli and not any other EVM chain. If you drop your solidity version down to 0.8.19 it should work other chains.
