Thanks so much for the suggestion and that would be the natural reaction to reach that control and delete it. It could also be done via the left side navigation area by right clicking the control.
But my problem was that the control contained a very very very complicated OnSelect property which I slowly built up in two-three weeks' time, I just couldn't risk deleting it.
However, I found a way. I just disconnected my internet after the screen loaded. The control started populating the collections without internet, and kept trying. I reconnected for a few moments and cleared the onvisible property of the screen. Saved the app in the same second and the problem was gone.
Anyways, it is always a pleasure in speaking with professionals, especially when someone takes time to help you out. I am an accountant by the way and very new to powerapps, but I am in love with the community here.
