DefaultLinkGenerator Fast Clicking = [Debug] Failed to process the template

Something more of an annoyance, possible bug? Clicking a SUBMIT with POSTBACK, including a screen lock on first click, when the page loads if you spam click the button to say, remove many items one at a time, one click per, you eventually get this strange DEBUG message and it boots you to logout. Some kind of SPAM protection or just a routing speed issue? I have tried hard naming the asp-area, asp-controller along with the action but it seems to happen randomly for end-users.

Yes our design could be better but this is a strange one. You can get the same action by hitting refresh too much on a single page as well. What am I doing wrong? Only is an issue when speed/spam clicking or spam refreshing.

Latest NET 5 CORE SDK 5.0.5, really nothing 3rd party. Just simple MVC with a touch of Razor.
