It looks like the string "animal well build 16245418" is likely a reference to a specific build or version of the indie game Animal Well (developed by Shared Memory / Billy Basso, published by Bigmode).
Here’s what that likely refers to and how to find a relevant report:

This is a minor but welcome change for the game’s growing portable audience. The “Ink Dog” Entity The most tangible addition—and
A vertical shaft normally requiring the disc and yoyo to ascend becomes, in this build, a recursive audio space. Each jump’s landing sound repeats with a delay that increases nonlinearly: 0.5s, 1.2s, 2.7s, 6.1s, etc. After the fifth jump, the delayed sound originates from behind the player’s physical position, implying a mirrored player entity.
