PermissionDenied, message: "Access is denied." at remove file after read on Github Action WIndows about memmap2-rs

Isn't that how Windows generally behaves, i.e. that opened files cannot be deleted? (I think it is more forgiving w.r.t. to the mappings.) So I think you want to call drop(file); before calling remove_file in your test? Possibly even drop(mmap); but I am not sure about the second one.

Theoretically, that's the case, but what confuses me is that on my local Windows 11 machine, I can delete the file normally without needing to drop mmap. However, only on Github Action's Windows Server 2022 does it throw an error. I will try to set up Windows Server 2022 locally for testing. I suspect that the difference in how Windows Server 2022 and Windows 11 handle memory mapping might be the cause.
