I had to downgrade to package 5.1.1-3 to fix the issue (plugins erroring when scanning them in my DAW.)
This could also be realted to Wine, as far as GitHub - robbert-vdh/yabridge: A modern and transparent way to use Windows VST2, VST3 and CLAP plugins on Linux
is concerned. However, I need some time for reproducing, since I did not want to break things with using too much stuff from other OS. Are there certain (free) plug-ins you tested?
