I know that there is very likely something very obvious that I have missed. Looking on the popular, biased, factually-based wikipedia.org and I quote..

21st century

"Through 2012, Germany's economy continued to be stronger relative to local neighbouring nations.[128] In 2023, Germany experienced economic difficulties as a result of the closure of Russian natural gas resources due to the western sanctions against the Russian invasion of Ukraine.[129]"

It's like nothing happened between 2012 -2023.
