My camera image aspect ratio is wrong.

Hi, all.

For a week now, the image shown of me in my gallery view is squished. You can see in the attached screen capture that my gallery image is distorted while the image in the video parameters is OK. How to fix this? I am using a Google Pixelbook Go Chromebook and the Zoom WPA. It was fine until about a week ago.

Thanks in advance for any help you may give me.
