Action: android.intent.action.MAIN
Cat: (leave none)
Mime Type: (leave blank)
Data: (leave blank)
Extra: de.blinkt.openvpn.shortcutProfileUUID=sdfsadf-sdfa-dfdf-dsfdsaf-dfdsfdafsd (removed that "S." at the beginning, seems weird)
Extra: de.blinkt.openvpn.shortcutProfileName=(whatever?***)
Package: de.blinkt.openvpn
Class: de.blinkt.openvpn.LaunchVPN
Target: Activity (I think. Try the other two if it doesn't work)
If you can't get that working, I'm a bit more comfortable starting intents from shell. In Tasker, choose action Script -> Run Shell and for command put:
am start -a android.intent.action.MAIN --es de.blinkt.openvpn.shortcutProfileUUID=sdfsadf-sdfa-dfdf-dsfdsaf-dfdsfdafsd --es de.blinkt.openvpn.shortcutProfileName=(whatever?***) -n de.blinkt.openvpn/.LaunchVPN
***From the java code it looks like you should have another EXTRA called de.blinkt.openvpn.shortcutProfileName, but I don't see it in the shortcut intent in your first post.
