Had this problem with both Synapse and Chroma crashing, I uninstalled Chroma and now Synapse works fine. Obviously not suitable for anyone who uses both but I only use Synapse.

I’m having 2 issues with Synapse 4, that I never had with Synapse 3. My Headset cord is finicky and doesn’t like to be bumped, that was normally dealablem, it’d disconnect and reconnect and I’d be good to go. Now after it disconnects, 95% of the time, it randomly turns off the Mic in Settings, not just making the Mute Button active, nope turns it off in Synapse 4’s Settings. It’s also arguing with my PC about being connected, when I haven’t even touched it, and sometimes the only way to make it stop, is to restart the PC.

The second issue, is 95% of the time I start up the first Game of League of Legends, and suddenly after it’s been working, Synapse 4 shutdowns, and suddenly my Profile isn’t active and I’m trying to use an Ability that is no longer there. And when you’re playing a MOBA like League of Legends, having your Abilities no longer be there, more often than not will lead to you dying.

I’m going to change it back to Synapse 3, as I never had these issues in Synapse 3. Even Microsoft makes sure their OS is in better functioning condition, before forcing people to upgrade to it. I have no Synapse 4 Products, everything I have is Synapse 3 generation, and as much as I love Razer, I love being able to actually Game, without interuptions from my Peripheral Software playing up daily. If this doesn’t get fixed, I'll be looking at different Brands for my Peripheral setup. Such a shame that they’re allowing their Products to be ruined by Malfunctioning Software, to the point we can’t even use the products at times.


To fix this Im guessing theres only certain devices that go RGB, and I have one of those devices, so you just have to uninstall the chroma when uninstalling razer. FYI macros dont save on synapse 4

i’ve read every comment. NONE of you hit the mark. Razer needs to fix their software. Not only does it crash, it corrupts the profile on your onboard memory,  Alters hit reg and click accuracy in games. changes mouse behavior.  The problem for me Started with Synapse 4. I get stutters and when going up in polling rate and swiping the mouse theres unbelieve screen freezing and lag. ( shouldn’t be happening on a top gear pc)  One day i decided to download synapse beta. Reset viper pro 3 to factory. uninstalled, deleted folders, restart pc, and downloaded synapse 3 to then set up my profile wallah problem solved. no lag when moving up in polling mouse behavior and hit reg in games normal. HOWEVER i realized mouse behavior kept changing on its own. so then came to the conclusion that i had to disable and stop razer game manager. that stopped the mouse from changing behavior and remaining normal exactly how i wanted it. 2 weeks later here i am trying to get on synapse beta to factory reset my mouse again which required me to turn game manager back on to open synapse 3 and uninstall etc. The problem came back the moment i turned it on but Synapse beta wont open now. It did open the first time i downloaded it and worked perfectly fine. same with 4. no issues for months and now its an issue. fix it or at least figure out what you guys did to make the programs so unstable.  synapse 3 is STABLE and allows my brand new viper pro 3 to act like its normal self.  I just can’t factory reset in synapse 3. and I have a brand new top of the line pc, never installed any RGB software and uninstalled/disabled any RGB that came with the pc. Never used any other razer app other than synapse for the mouse. I did notice razer central service never opens and that could be the issue. i’d just like Razer to really figure out what the trigger is because prior to the jan 27th update synapse beta worked fine. razer 4 started crashing days prior to that 2 weeks ago.
