MPC Software VST/AU really M1 compatible?

I recently switched from the last iteration of the i9 Macs to an M2 Pro Max. I installed everything from scratch. This includes MPC Software as well as the MPC VST/AU plugins for other DAWs. In that process I installed the M-only version of Studio One because all VSTs I use are M-Mac compatible ... as is claimed by Akai for their Software as well. But now this: The MPC VST and AU are found and listed in Studio One but when I drag them over or add them to a track nothing happens. On the i9 Mac they of course worked. Does anybody else have these problems? And maybe a solution that does not force me to install the intel version of S1?
The SW version is 2.12.2.55
