Camera link with Google home pin code issue

Finally i got my Eufy cameras linked to google home. 2FA pin you have to chose yourself (6 digits). Then Eufy security cams are linked to GH. I diabled GH 2fa.
When i want to see my Eufy cam view on the GH screen, it worked by just saying camera group on. But GH ask me for the self made up PIN, when i say the pin GH tells me the pin is wrong. At that moment it is showing the cam view, but because of the not wrong pincode the system hangs and i cannot turn it off anymore. Am I the only one, why is this so dtamatically working. Eufy we need your technical backup to explain what to do or solve it!!!
