How do I fix Android emulator crash from "failed to sync vcpu reg"

Question

I am using Android Studio emulator, but it keeps crashing upon opening. I get failed to sync vcpu reg error multiple times in the output and nothing else.

I have tried the solutions to similar questions posted on here to no avail. I tried: reinstalling HAXM, I don't have the docker application, I used BIOS to check that VT-x and VT-d are both enabled. I don't get any logcat from Android Studio.

Attached is picture of the output from running the emulator from cmd

This question is different from apparent duplicates because my emulator worked the day before. I don't have any virtual machines running. The only difference is that my laptop auto updated last night.

Answer 1

I am using Windows 10 and tried almost everything the internet had to offer to fix this issue (the Virtual Machine in Android Studio loaded but then closed almost immediately)

The fix I found was to enable "Virtual Machine Platform" on Windows features.

Instructions:

1. Right click on the Windows button and select 'Apps and Features'
2. Select Programs and Features on the right under related settings
3. Select the checkbox below

CHECKBOX TO CLICK

You then get prompted to restart - after that, everything worked for me ! ...hope it does for you !

Answer 2

I solved this problem on my HP laptop by uninstalling HP SureClick.

Answer 3

I had this same problem and all the solutions here did not appear to fix it. Strangely enough I managed to fix it by turning windows virtual machine platform ON, even though it very specifically says here that this is something that should be turned OFF.

Answer 4

I tried what paulsm4 said and the emulator works now. I was looking around in my anti virus settings and found something that uses virtualization. I just turned it on rebooted and then back off and rebooted. The emulator runs!
