Not sure if this is the same exact issue or not, but I fought this same message for a very long time. I have actually come across this now twice.
The first time it was on a network that was wired terribly, new switches were ordered, and new cables had to be run.
The second time was when a client was on a terrible WIFI router.
From what I can tell with 2020 it takes longer to "log in". You actually get the launcher fully up before everything behind the scenes is done logging you in and giving you a valid session. On slow networks or networks that occasionally hiccup and cause things to temporarily pause its possible to click on screens before you are fully logged in.
The temp work around was to ask users that get the issue to wait 30 sec to a min after they log in before the start trying to use the system.
