Keyboard is blocked in Games

Hi,

I got a Razer Deathstalker and a Razer Naga.

My Naga is up-to-date on the Razer Cockpit, but my Deathstalker is a bit older and is managed on Razer Synapse. They worked very well for years since yesterday: My Keyboard is complete blocked (like it is not plugged in) when I open a Game. It dont react to any buttons, but shows the lightning on the keys. And sometimes (rly rare) the mouse stops working and the keyboard works. When I close the game, it work fine like usually.

I searched for this topic and cant find a answer. Yesterday my Razer Software updated and since this point, it happend. I looked for Updates, it is on newest version. I plugged the mouse and keyboard in and out, restartet, reinstalled the software, nothing works... iam so frustrated at this point. I dont know what to do...

Edit: When I open Spotify or Microsoft Teams the Keyboard also complete stops working. If I close the Software, it works again.

Need help to fix.

Kind regards,
Akoo
