Razer Synapse 4 input stuck, delayed or not registered

Sometimes, when I'm just typing or playing games, inputs won't get registered or will be extremely delayed. But the most frustrating thing is that sometimes keys are still 'held' even though I let go of them seconds ago, and remain pressed until I press them again. I tried killing all Razer services running on my PC (Synapse, etc.), which solved the problem, but the keyboard was no longer usable because of the Razer software not running.

Same. I am playing Overwatch. I just got my Razer Blackwidow v4 low-profile keyboard  with Razer DeathAdder v3 Pro mouse. The AWSD key or something will just stuck in the mid game when I have an intense fight (which use both mouse scroll + holding mouse right click + shift + AWSD). The only way to fix it temporary is to alt+tab out the game and back.

 

I am using Synapse 4 with the Sep 8, 2025 update. 

 

Any fix to the software yet?
