So macOS Catalina drops 32Bit support it I cannot use it anymore.

 

Is there a way to get EOF 64Bit for macOS?

I don't think it will be feasible to rebuild EOF and all of its dependencies as 64 bit. There are consequences caused by Apple's progress for the sake of "progress" instead of actual need. You might be able to run it in a VM or something, presumably there will be lots of Apple users who still want to run 32 bit software.
