These symptoms sound like an issue that has been reported and now fixed related to certain plugins crashing Code: https://github.com/elementary/code/issues/619

A new version incorporating the fix was released in early March 2019.

For future reference, it is possible to reset all of Code's preferences to default with the following command in the terminal:

dconf reset -f /io/elementary/code/

This often resolves issues with code relating to plugins or documents its trying to re-open that are causing issues.
