I managed to connect the SR1 with ScriptPlayer through Intiface. This tutorial helped with it → OSR2/SR6 to Intiface Central connection unofficial rough guide - #4 by Ratattack15
Seems you like you have to start scanning for devices in Intiface first and then connect the SR1 via USB. Then it shows up. Before I always had the SR1 connected before and then I searched for devices and it didn’t show up. Doing it the other way around works.
