Hi @Gregory.Hunter,

Thank you for reporting this issue. There seems to be an issue with Rtools 4.3.0 that is currently still classified as development version. We tested with R 4.3 and Rtools 4.3 and we got an error but a different one. With R 4.2 and Rtools 4.2 it worked without issues.

We will try to find some workaround to avoid these issues, but it may be something that will only be fixed with a new release of Rtools.

Thanks, @fdabrandao. I’ll roll back to 4.2 for now.
