Hi there, Let me preface this by stating I contacted Razer's support regarding the issue I'm about to describe. I was told (I'm paraphrasing) that they didn't know what was wrong and didn't have a fix for me. I'm hoping someone will read this and let me know I'm not the only one with this problem. It all boils down to this: Somewhere in the middle of the release of Synapse 1.18 it began randomly crashing. I go about my web browsing, gaming, etc. and my Chroma keyboard and mouse pad seem to be working fine with my loaded profile. Suddenly, I'll hit a macro key to perform a function and realize that Synapse has crashed without warning. The icon remains lit in the system tray until I hover over it and it disappears. I then have to restart Synapse and everything resumes as normal until the next random crash. I am seeing unhandled exception errors for .NET directly related to Synapse when the crashes occur. The following is an example of the persistent error I receive: Application: RzSynapse.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.AccessViolationException at MS.Win32.UnsafeNativeMethods.DispatchMessage(System.Windows.Interop.MSG ByRef) at System.Windows.Threading.Dispatcher.PushFrameImpl(System.Windows.Threading.DispatcherFrame) at System.Windows.Threading.Dispatcher.PushFrame(System.Windows.Threading.DispatcherFrame) at System.Windows.Application.RunDispatcher(System.Object) at System.Windows.Application.RunInternal(System.Windows.Window) at System.Windows.Application.Run(System.Windows.Window) at Razer.Emily.UI.SynapseApp.Run() at Razer.Emily.UI.AppEntryPoint.Main(System.String) These are 1026 event IDs. I am running Windows 10 and cannot uninstall .NET 4. Both Microsoft's repair and validation tools say .NET 4 is in proper order. If the culprit is .NET, the only solution is to reinstall/reset Windows 10. I will do anything but that. I really appreciate any help or ideas!
