Monterey Memory Leak

Early adopters of macOS Monterey are reporting a memory leak, where Apps that are quit continue to run in the background using RAM. I have experienced this on my iMac running Monterey 12.0.1. My RAM just seems to disappear. This article describes people experiences with this problem. There is no known fix at this time short of the Monterey 12.1 update, which is currently in Beta.
