Crop Defaults to Locked Original Aspect

[minimejdh]

I am using Lightroom Classic v 13.0.1 on a Macbook Pro.

The crop tool defaults to the Original Aspect and is locked.  If I want to change the aspect ratio I first need to click the lock icon to unlock it.  I did not have to do this in the past. The lock default appears to have been added relatively recently.  
Is there a way to change the default so it is not automatically locked?  

Also, what is the difference between the Original and As Shot?

Thank you.

Try this-

1) Open the Crop tool by clicking on the crop icon

2) Click the padlock to unlock it

3) Immediately exit the Crop tool  (by again clicking the crop icon)

I think you will find that the padlock is now in the unlock default state the next time you use it.

"Original and As Shot?" Are you referring to White-Balance?

"what is the difference between the Original and As Shot?"

For cameras that let you shoot or crop in-camera at aspect ratios different than the native ratio of the sensor, Original is the sensor's aspect ratio and As Shot is whatever you set in the camera.
