The errors you are encountering during the compilation of your Cairo contracts seem to be related to syntax and import issues.
Cairo 0.4.0 is required i think.
Of course you should make sure that your contracts are written in the correct syntax according to Cairo 0.4.0, i suggest to review your contract files for any syntax errors or outdated constructs. Don't forget to update contract dependencies as well.
After making the necessary updates to your contract code and dependencies, try to recompile your contracts using the new Cairo version.
