Camera spinning out of control when following cursor

SuperSpark

I'm trying to setup a new project in Unity 6. The game is a first-person point and click where you click on things and interactions happen and I want the camera to move very slightly by following the cursor. Unfortunately, for some reason the camera will start quickly spinning in random directions the second the game starts as long as follow cursor is enabled. I've used all the constrain and lock tools that I'm used to using in previous projects but it doesn't matter what is and isn't locked or constrained, it will spin out regardless as long as Follow Cursor is enabled. What is happening? Has the way the camera works changed?

You mention first-person - are you specifically using the first-person camera / movement mode, or is it just a Standard 3D camera?

There hasn't been any recent change to a camera's "Follow cursor" option, though there are now two input handling options. Are you using Input Manager, or Input System, and - if the latter - AC's integration for it?

Does this issue occur if you in the 3D Demo scene by enabling the same option on NavCam1?
