Hi folks,
the issue is that Chrome is unable to open any page. It hangs. Unable to quit Malwarebytes either. Then unable to restart a laptop - only hardware power off / on.
I made sure this is CU12 specific by removing the beta and placing the latest official release back in place. The issue was gone. Placed CU12 back - the problem returned.
No special steps to reproduce needed. Reboot a machine and launch Chrome. Here you go.
The only workaround to access Chrome was to reboot a machine, quit MB3, run Chrome, then run MB3.
FRST and MB-Check logs are attached.
