I recently experienced a situation where Android Studio’s emulator crashed when starting an app that performed basic graphics operations.
Crash reason: EXCEPTION_ACCESS_VIOLATION_WRITE Crash address: 0x66720000 Assertion: Unknown assertion type 0x00000000 Process uptime: 13 seconds
I started up Process Monitor to investigate the issue.
Tried recreating the situation, then stopped capturing events with: File -> Capture Events
Wanted to get an overview of the processes involved with: Tools -> Process Tree…
Right clicked studio64.exe and selected: Add process and children to Include filter
Noticed that emulator64-crash-service.exe left a memory dump under:
Examined the memory dump with WinDbg (x64).
Checked for details about the crash with:

This indicated that the problem was related to graphics drivers and/or settings.
I did not have important data on the Android emulator, so I made it boot again by removing all data (including the auto-starting app, which crashed the emulator).
Did this in Android Virtual Device manager with the Wipe Data option.
When the emulator could start again I started looking for additional graphics settings.
Found some under Extended controls -> Settings section -> Advanced tab.
The default setting for OpenGL ES renderer (Autodetect based on host) seemed problematic on this system.
I experimented with the settings and discovered that SwiftShader worked well. Running graphics rendering apps with this setting no longer crashed the emulator.
The problem occurred on a desktop system with an Intel Skylake CPU (Core i7-6700) running Windows 7 using Intel HD Graphics 530 with driver version 18.104.22.16860.
If Android Studio’s emulator crashes when running graphics rendering apps, it may help changing the OpenGL ES renderer setting.
