RazerAppEngine causes Huntsman Analog V3 TKL USB firmware state corruption after Windows forced shutdown paths; keyboard fails POST until USB reconnect.


I’ve searched all over and seen similar issues but not exact and no resolution. Hoping someone else seen this or knows fix. Any Thoughts?

Problem: When I do a forced windows shutdown (shutdown.exe /s /f /t 0) with Synapse App Engine running, the keyboard does not initialize during POST or when Windows starts. I have to unplug the usb and back in to get it to activate.

However If I exit the Razer Synapse app then do forced shutdown, the keyboard initializes fine during POST and Windows load.

Few work arounds I found:
1) Leaving synapse running but using another brand keyboard attached doesn’t have this behavior (did this just as test)
2) Shutdown /s /t 0 (not forced) has no issue with Synapse.
3) Also doing shutdown using Start > Shutdown has no issues with Synapse running. and KB works find in POST/WIN
4) Yes I can stop doing the forced shutdown but I have it as part of script to execute when certain triggers occurs. For now I’ve created script to kill all RazerAppEngine processes before issuing the forced shutdown.

Keyboard: Huntsman Analog V3 Optical TKL with latest firmware (model RZ03-0498) [fw v1.04.00_r1]
Razer Synapse v4.0. [removed by moderator] (latest)
OS: Windows 11 Pro (all latest updates as of today)
Motherboard: ASUS STRIX X870E-E latest BIOS (no BIOS tweaks, default settings)

I did find similar thread but it’s old and no resolution,
