I am having similar issues with memory leak using just the standard Cura software (3.5.1), Octoprint is not installed (AFAIK). I tend to have SolidWorks running on my PC all day most days and it has a 'Resource Monitor' facility, which notifies me when the RAM is running low, helping to avoid crashes. The leak seems to happen if I leave Cura on the Monitor tab with the Video feed turned on. The last time this happened, I was able to stop and start the 'leak' by turning the feed on and off by clicking the blue camera icon in the Monitor tab sidebar.
