@nielso @x42 @PaulDavisTheFirst wine breaks quite often when it comes to windows vsts, because we rely on winegcc/winelib to set up a wine <-> linux communication.

it is not windows tools talking with other windows tools, it is windows tools talking to native linux tools and vice-versa.
involves a bit of wine internals which can change with time.

the best possible advice I can give is: if you have a working wine version, dont update! and stay away from wine-staging for audio plugins
