Can not receive gmail e-mails

Hello, as others, I can not receive gmail emails for few days.
I have deleted my account, closed, restarted, created the account anew, but still get the red triangle next to the gmail account with incorrect setting warning. The setting shall be correct, say my chrome browser, as the rest was cared for by the setup itself.
Can see similar posts here, like this one Gmail not receiving! , but when I try to run the emstackdump.exe, I get several various errors with reasons, why it could not be started.
Desperately yours,

As a test, can you completely disable any anti-virus, firewall, proxy or VPN, then try again.
Sometimes even restarting your router may resolve this.
