Search – CoreResultsWebPart will stop working in 2019

I am currently working on a migrated 2019 farm. The migration took place in 2010-> 2013-> 2016-> 2019 in one go.

Now I find the old one CoreResultsWebPart No results are displayed at all. The search works fine and if I remove the CoreResultsWebPart and replace it with the new one ResultScriptWebPart Results are displayed.

Is it possible that the old ones CoreResultsWebPart does 2019 not work at all?
