A Circular Dependency can occur when you try to create dependencies between Tasks that already depend on each other, either directly or indirectly, creating a loop. For example, if you have two Tasks with a pre-existing Dependency, you cannot create any other Dependency between them. Doing so would create a feedback loop where the Tasks constantly and repeatedly update each other due to multiple looping dependencies. When trying to create such Dependencies, you will receive an error message.

Sometimes even when Tasks are not directly dependent on each other, they may have Dependencies with other intermediary Tasks making them indirectly dependent. In such cases, trying to create another Dependency between them can also lead to Circular Dependencies.
