The hole was caused by our use of CFCs, especially in refrigerants. We banned the use of CFCs globally, allowing the hole to close up. A perfect example of man-made damage to the climate being recovered by coordinated international action.

There's a good BBC article about it: https://www.bbc.com/future/article/20220321-what-happened-to-the-worlds-ozone-hole
