Morning, I notice that the one in the background has printed fine :) From the look of the print it appears you have used a cool plate and not the textured PEI as recommended, they really are a different beast and can cause adhesion problems for users - as youve experienced. With the Keyring we find that a lot of people wish to resize to their own specifications, you can also do this in Bambu Slicer and make it to the dimensions you prefer. Thank you for the comment although 2 stars is very harsh.
