Prevent infinite loops in Flows

Describe the Bug

I'm using community cloud. ~ v 9.21.2

When a flow is created using the Event Hook trigger, with "create" scope and includes the Directus Activity table, a infinite loop is created, because records are created in that table when ever flows are executed.

The outcome is the project eventually crashes.

There are similar issues discussed but I don't see a use case where a flow should execute based on the "Directus Activity" table as it would always create an infinite loop.

To Reproduce

Create Flow.
Trigger: "Event Hook"
Type: "Action"
Scope: "Create, Update"
Collections: Directus Activity and Any other

Once this flow is triggered, it will continue executing until the project crashes. The flow then needs to be removed immediately otherwise the infinite loop begins again.

Infinite loops are not something we can completely prevent however you can prevent this by disabling the activity tracking for the flow that is watching that collection

Not sure if this can be classed as a bug but it's worth noting is somewhere.

Just experienced this myself and had no clue until I tracked it down to me not completing a flow. It actually broke DO App service. They had to manually reset a service. 🥼
