[Doctor Strange 2: the Multiverse of Madness] Why couldn't Dr. S stick Wanda in the escape proof prison cells below the Sanctum like he did with other villains in No Ways Home?

"Escape proof" isn't really a thing when your target can literally author her own reality on a whim. Kamar Taj _tried_ to trap her when she first invaded, but she found a loophole and quickly escaped.

Her improvisation was more powerful than the magic of the Sorcerer Supreme.

Wanda is basically the most powerful magic user in the MCU, because Chaos Magic's rules are more like suggestions than hard limits.
