No cloud project ID was found

My last project has been created with Unity Version 2018.2.7f1 offline without any internet connection (our proxy blocks everything).
After updating Unity to Version 2021.3.11f1 when opening the project I get the error “No cloud project ID was found by the Analytics SDK. … Please make sure to link your cloud project in the Unity editor to fix this problem”.

How can this happen? I do not have any project ID and I am not able to get access to internet with Unity to use cloud services. How can I get rid of this error?

Is your project settings is set on ur ID? if its not then set it on ur ID.
