a picture of the actual bike would be helpful
That is called chain suck, and it can happen because of drivetrain wear, especially if your chainrings are worn more than your chain.

The bearings on the chain are bent. Does it happen around the chain link?
Does your real derailleur have a clutch?

My Grizl does. If so, engage the clutch… that’s exactly what the clutch is for.
Cheap derallieur with no clutch would be my guess.
Bent teeth on the chainring
Happened to me just today. A few teeth of the inner chainring were bent inside. Just a bit. But it caused enough friction so the chain got stuck on it.
Burr on the chainring tooth
New chain?
Chain suck sucks.
