Failed to start Renoise as ReWire slave (Windows 11)

I’m on Windows 11 Pro (22621.963) trying to Rewire Renoise (3.4.2 win64) to Reaper (v6.72 win64) as the master.


What could be the issue here?

I just found out that Rewire has been (silently?) deprecated for a while.
The question then is, what is the modern way of connecting Renoise to Reaper, that is recording the individual outputs of multiple channels to separate tracks in Reaper?
