A Steam user suggests that the issue may be related to EA's Anti-Cheat system. As a temporary fix, try manually launching the file named EAAntiCheat.GameServiceLauncher.exe. You can find it here:
C:\Program Files (x86)\Steam\steamapps\common\Skate
Alternatively, right-click Skate in your Steam library → Properties → Browse Local Files to locate it.
This workaround reportedly helped in at least one case, but it's not an official solution from EA and may not work for everyone.
