Character not moving since updating to 4.26.1

Hello,
i just updated the engine from 4.24 to 4.26.1 and suddenly characters do not move anymore. They’re also stuck in the air.

Doesn’t matter if i use the default pawn / controller, spectator or my own pawn.

APawn::AddMovementInput is getting called with the proper WorldDirection + ScaleValue, so input itself works.

It’s more or less a fresh project, what is going on?

Thank you.

Can you share your code?
