The book Socialism Betrayed is an excellent book if you want to understand the reasons for the collapse of the USSR (Chernobyl was not a major factor, but I wouldn’t say it had zero impact). Or, if you would prefer to read a book not written by Marxists, Revolution From Above would fit that and IIRC the authors of the later largely come to the same conclusions as the former.
Much like the collapse of the Roman Empire, it’s a very complex topic that isn’t easily boiled down into simple answers.
