You can use to the Legacy mode to view data collected from versions of Unity before 2022.2. This mode displays an older version of the Physics 2D Profiler module, which was the default module in versions of Unity before 2022.2. To change mode, select Legacy from the dropdown menu at the upper-left of the Profiler module’s details pane.
In this mode, you can load and inspect Profiler data that was saved in an older version of Unity. You can’t use this mode to display data from newer versions of Unity.
