Thanks @cyberzork, I’ve uninstalled all security software from my Win10 machine, only thing left is the built-in Windows security which I can’t uninstall and I’ve added the eM Client executable to the apps whitelist.
Settings are but I still get the same issue:
I’ve repaired the installation to no avail, I’ll try unisnatlling and reinstalling eM Client.
Are there any Windows 10 security settings I can tweak or disable?
