If a cat is particularly timid, you may need to let the cat adapt to the environment first, and then play with the cat more after getting familiar with it, so that the cat can trust you. This can alleviate the timidity of the cat. Usually don't make big noises to avoid scaring the cat; if a stranger comes to the house, it's best not to disturb the cat, and don't force the cat to avoid stress reactions. It may get better when the cat grows older.
