upsets the applecart

Throws everything off

Upsets the applecart means to disrupt a plan, system, or stable situation—especially one that was working smoothly.

The image is of a cart full of carefully arranged apples being knocked over, scattering everything: We had the whole project mapped out until the new regulations upset the applecart.

Often used when someone or something introduces unwelcome chaos into settled arrangements.
