Knime crashing and shutting down so much since I upgraded to 5.5.1

My coworkers and I have flagged a new behavior with the latest versions of Knime. If you leave it idle for a while and do other things or leave your computer, Knime will shutdown and lose all of your unsaved work/executed nodes. Not all the time, but it’s happened several on occasions since I upgraded to 5.5.1. I also just had Knime crash and shutdown out of nowhere while running a workflow, not idle. This all seems new to the latest updates. Is this happening to others? It’s very inconvenient behavior for complex workflows that need a lot of time and storage to run.
