Hi,
So far, the only similar reports I’ve received were caused by Avast incorrectly flagging meshoptimizer.dll as a threat. The DLL is built directly from the official meshoptimizer sources on GitHub, so unfortunately I’m not sure why some antivirus products are detecting it.
A few users were able to work around the issue by adding the DLL (or the SDF Modeler folder) as an exception in their antivirus software. If you’re using Avast or another security product, it might be worth checking whether the file has been quarantined or blocked.
At the moment there’s not much I can do on my end beyond investigating alternatives for future releases.
Cheers,
Sascha
