GameManagerService3.exe Still Crashing

October 2025 -- Over one month later and I too can report that GamerManagerService3.exe repeatedly crashes Windows 11 Pro 25H2 (OS Build 26200.7019). 

Before my problems with GamerManagerService3.exe, there were repeated crashes immediately preceded by failures of Razer Chroma SDK Service Host. At the time, I had both Chroma and Synapse installed, so I uninstalled Chroma and repaired Synapse just in case. This avoided failures of Razer Chroma SDK Service Host, but now crashes are immediately preceded by failures of GamerManagerService3.exe. I ran DDU to uninstall my Nvidia GPU drivers then cleanly reinstall the same drivers, but with no effect on failures of GamerManagerService3.exe.

I will uninstall Synapse until Razer resolves this problem. This will sacrifice functionality for my three Razer products: BlackWidow V4 keyboard; Tarturus V2 keypad; and Basilisk 35K mouse. Very disappointed.

The log from System Reliability Report will be familiar to the numerous others who have had the same problems with GamerService3.exe:
