for those who are still looking for an easy, stable solution, try this:
https://github.com/DISTRHO/Ildaeil
install Ildaeil as a vst2 synth and effect (synth and effects are two separate vsts). Load it up, and on the top right there’s a button that asks which plugin type you want to load – VST3/CLAP/LV2/etc. Ignore all that and select the option that asks you to select a file. Using that option, find a plugin of your choice and the synth/effect will be loaded up, ready to use. When you save your project, the VST3/CLAP/etc will be saved too.
