Razer Synapse 3 Installation Failed on Windows 11 21H2 (22000.194)

Hi, I have a clean install of Windows 11 21H2 (22000.194) and I'm currently not able to install Razer Synapse 3 on it. The system is up to date. I do realise that there is no "official" version for Windows 11 available yet, but when is it planned to be released? No other software/hardware is having issues on my PC. The installation reaches about 40-50% and then just crashes without error pop ups. I have tried launching the installer multiple times as either regular user or admin with the same result. Event log for the Razer Synapse 3 install failure Faulting application name: RazerInstaller.exe, version: 1.0.150.988, time stamp: 0x612270cf Faulting module name: ksproxy.ax, version: 10.0.22000.120, time stamp: 0x8dfa3d64 Exception code: 0xc0000005 Fault offset: 0x0003802f Faulting process ID: 0x740 Faulting application start time: 0x01d7ad93eaf01099 Faulting application path: G:\\path\\RazerSynapseInstaller_V1.0.150.988\\RazerInstaller.exe Faulting module path: C:\\Windows\\System32\\ksproxy.ax My Razer keyboard, mouse and web cam work, but Kraken Ultimate headset keeps disconnecting with the following error in Event Viewer.

I have found the solution to my problem. Cause: Plugged in headset - Kraken Ultimate Solution: 1. Unplug the headset 2. Uninstall Kraken Ultimate driver in Device Manager 3. Do not plug Kraken Ultimate yet! 4. Install Synapse software (RazerSynapseInstaller_V1.0.150.988.exe) -> this time it succeeds! 5. Launch Synapse and login (it may offer an update) 6. Plug in Kraken Ultimate 7. All working all dancing

Have had similar problems due to various USB devices plugged in during updates. Even had a PC hang during startup because of a problem initializing a USB device. Unplugging external devices and in some cases deleting device drivers and letting them reinstall solved most of these problems.
