Looks like I can use UADx plugins now. They have some GUI related crashes, like the Arturia plugins, but when they are dialed in, you don't need the GUIs anyway - so I'll live with that. This has been fixed in Wine 11, but those fixes has not yet come to Proton/Wine-cachyos, so I'll have to wait.
Solution to install: Get UA Connect on your Linux and a PC, install everything on the PC, move files to your wine-folder and activate the plugins in UA connect through wine.
