llNotFoundException: nanosockets assembly:<unknown assembly> from Editor in Windows

Options

Hello!!

I'm having this exception:


DllNotFoundException: nanosockets assembly:<unknown assembly> type:<unknown type> member:(null)


I know it happened in the past to some people in builds for different platforms but, in my case, is raising from the Unity editor running in windows, in unity 2021.3.4f1 and with Fusion 1.1.1 (also tried 1.1.2 and same result).

It has been working for months from the editor and even for windows builds but yesterday, suddenly, this started to happen. We are not aware of any change on our side that might be causing this and we even went back in our repository to previous working versions only to find the same problem.


We are blocked with this since yesterday... can anybody lend us a hand?
