But the link tells you the details and how to solve the problem.
Anyway, I think you forgot to share the said screenshots. I can't find them.
Also, when you are asking please, don't try to direct us how we should solve this problem. Just detail your problem and wait for your answer.
Simple.
A circular import happens when you have fileA that has something say a class A, then another file B with also a class B
Then class A imports class B from file B which is also importing class A from B.
So the program keeps importing and never completes the cycle.
Solution,
If you have to use the two like that, then put them in the same file. It is always my shortcut.
