Firewall and Autodesk CER Service

[Bjanders]

I just started Fusion after the latest updated, and got the following prompt:

What is this service, and why is the Publisher unknown? I denied access, as I don't know what this is.

Unrelated to the firewall prompt, but Fusion also crashed before it even fully started.

CER stands for Crash Error Report.

It sounds like Fusion crashed, which started the CER service, which Windows Defender takes exception to. It's safe to allow Autodesk CER Service to run.
