Octave uses some linear algebra libraries that are written in Fortran. By
default, integers are 32-bit wide in Fortran also for 64-bit targets. That
means some operations are limited to arrays that can be indexed with 32-bit
integers.
Having written that, it *is* possible to compile those Fortran libraries with a
(non-default) integer size of 64 bits.

Unfortunately, most of Octave's infrastructure is currently down due to an
unexpected server outage. But you should still be able to find that installer
on GNU's FTP server:
https://ftp.gnu.org/gnu/octave/windows/
The version you could try is "octave-7.2.0-w64-64-installer.exe".
I hope that helps.
