This is what we are experiencing in realms as well. I suspect it's a different character ID. I opened a new bug report because this does appear to be a different issue, as it is now all-the-time, in addition to impacting realms logins. My report was scoffed at and it is now associated as a duplicate. We will be requesting a realms refund since it is now impacting us in realms.

This happened to my son about a year ago. He was always the second player to log in. When his original character ID was disassociated in some way, he lost all inventory and access to anything in the enderchest. At first, it was random, which character he would log in with next. At that point, he started playing Roblox instead. Don't blame him either. I am not nearly as excited about the upcoming updates due to this bug. I am also no longer purchasing anything associated with Microsoft because of this.
