Mac user here - it looks like you are trying to add an already-unzipped FOLDER to the post. Note that "Kind' is Folder, not zip archive. Are you using Safari? There is a setting which is likely enabled which automatically unzips downloaded zip files. In Safari's Preferences -> General -> Uncheck Open "safe" files after downloading. You can either re-download the file with the correct settings, or just zip your existing diagnostics folder by right clicking it and selecting "compress".

Would love to get this resolved as I too am experiencing performance difficulties with Win10 VM on NVME passthrough. Win10 VM on VDisk is totally fine. I have been running my Win10 NVME Passthrough VM for years with no difficulties, but something changed at 6.12.8. I have reinstalled windows 10 on my NVME passthrough VM just to be sure it wasn't the OS.
Performance is normal enough directly post-boot but CPU idle is high at ~20%. Eventually, intermittent stuttering leads to unusable lagging and I have to force a reboot. Failure seems to be brought about more quickly if I load up demanding applications. The configuration on my VDisk VM is otherwise identical and performs flawlessly.
Will post diagnostics if there is bandwidth for resolving this. Please let me know what state the VM should be in before I extract diagnostics. Thanks!
