My browses aren't starting in the sandbox anymore.

I restarted and its till not working, its in the sandbox but doesn’t boot up. Using the latest version on Windows 10 64 bit.

Have you tried clearing the sandbox?

Yes and restarting the laptop. Oddly enough Virtual Desktop works no problem.

Found out the problem was Malwarebyte’s anti exploit was enabled and messing up the sandbox for some odd reason.
