Reason Uncaught Exception in GameEngine::update AND 64bit Zerohour

[MacNc2023]

hello
I support your work in reviving Zero Hour.

I have a few questions.

1. Why does this error occur?
   Below is the log record.
   Reason Uncaught Exception in GameEngine::update

2. I know that Zero Hour is a 32-bit game. Are there any plans to modify or develop it to 64-bit?

I understand that 32-bit only recognizes up to 4GB of RAM.

3. Can I try Zerohour with the changes made so far?
   I gave it a try after you told me about it before, but unfortunately I couldn't feel what had been changed. (I wonder if the revised contents are also documented)

I also want to study C++ and help with this project :)
