Before it was working fine, but after changing some settings (no I don't remember which exactly), no more rounded corners. I don't know if I'm doing something wrong but I've tried using default settings, reinstalling and restarting a lot of times.

Start in ExplorerPatcher's Properties → Start Menu settings and reproduce the Corner preference change on Windows 10 22H2 with version 26100.8457.70.4. Compare the Rounded Corners and Floating menu choices with the resulting Start menu appearance, then verify that the selected preference changes the corners without ExplorerPatcher-specific conflicts.
