Can someone help me find who this is?

I found this image as the thumbnail of a YouTube video and was wondering if anyone can identify who this person is.

Unfortunately, the video doesn’t mention her name, and she appears only briefly. This image is from the thumbnail itself, not an actual scene.

If anyone recognizes her, I’d appreciate the help. Thanks in advance!

Here's the video link: https://youtu.be/EOFeV6f9iS8?si=mUm3EO90230171xu
She only appears in the thumbnail and not in the main content.
