Julia has great Project + Manifest reproducibility, but it only applies when using the exact same Julia version – either 1.11 or 1.10 in your case.
On different versions, there’s no guarantee one can instantiate the manifest, exactly as you see in the error message.
Project.toml should often be possible to instantiate even on a slightly different version. It may easily result in different package versions though, so make sure to put your constraints into the [compat] section.
