Windows 10 (1903 and higher) with EAM regularly hangs at user login or before login on black screen with small blue circle. It begins around spring 2020.
We have >20 PC with Windows 10 1903/1909/2004 connected to cloud (at different accounts) and this problem periodically occurs on different PCs. To avoid this, we have to force boot in safe mode, disable the "Emsisoft protection service" and restart PC and we have normal boot. Enabling "Emsisoft protection service" and rebooting causes this problem again. Uninstalling EAM with uninstaller and "Emsiclean" and reinstalling after two reboots helps for some time. Often this problem occurs after installing windows updates and rebooting.
For testing purposes we tried to install clean Windows only with device drivers, latest windows updates and EAM connected to cloud and after some time and after another reboot (after installing windows updates) problem occurs again.
Unfortunately we had to uninstall EAM from all PC and PCs working without issues.
