scala monix tasks Scala

I've searched everywhere and can't find a clear answer. I'm stuck on something that should probably be simple. Hey everyone, I'm running into an issue that's driving me crazy. I'm stuck on something that should probably be simple. I'm working with an scenario with the Monix library in Scala 2.13, where a `Task` is being unexpectedly canceled before its execution completes. I have the following setup where I'm trying to create a chained sequence of tasks: ```scala import monix.eval.Task import monix.execution.Scheduler.Implicits.global val task1 = Task { println("Task 1 started"); Thread.sleep(1000); println("Task 1 completed") } val task2 = Task { println("Task 2 started"); Thread.sleep(500); println("Task 2 completed") } val combinedTask = for { _ <- task1 _ <- task2 } yield () combinedTask.runAsync ``` I expect both tasks to execute sequentially, but sometimes I see that "Task 1 completed" does not print, and I get an behavior message saying `Task was canceled`. I've tried wrapping the `runAsync` in a `Try` block to catch the failure, but it doesn’t give me any additional information. It seems like the cancellation happens randomly, which is puzzling. Additionally, I'm aware of the `Task`'s lazy evaluation nature, but I'm not sure how it could lead to a cancellation scenario. I've also tried running the tasks without any chaining and they execute as expected. Is there something I'm missing in terms of handling task execution or cancellation? Any help would be greatly appreciated! How would you solve this? Am I missing something obvious?
