I’m also encountering the same issue in UE 5.2.1.
Fortunately, it doesn’t corrupt the project files or the Perforce depot, but it’s still quite frustrating.
The “View Changes” window becomes noticeably slower, and submitting changelists turns into a real hassle.
To fix this, I reverted all the Uncontrolled Changelists and validated UE through the Epic Games Launcher. (it takes approx 5 to 10 mins)
However, new uncontrolled changelists keep appearing every week, which is quite bothersome.
