I change DNS to a public DNS, reboot my computer. Then Razer Synapse 3 can detect my Viper v3 PRO. I test many times, it works well. Maybe this issue caused by network reasons.

Bidnt update Nvidia driver. But windows update installed the following:
2025-10 Cumulative Update for Windows 11, version 25H2 for x64-based Systems (KB5066835) (26200.6899)
2025-10 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 25H2 for x64 (KB5066128)

Me too.

After installing KB5066835 and KB5066128 on my Windows 11 25H2, my Viper v3 PRO can’t be detected by Razer Synapse 3.

I didn't change my DNS settings. This morning It returned to work as normal.
I don't know what changed... (No Windows updates were installed either).
