Hi everyone! There have been a lot of conversations about the vst3 issues (especially with iZotope Ozone 9 and RX 8 Elements) since 16.1 and later...the issue is quite easy to resolve. The problem is that due to the re-hauling of the VST3 Engine, our vst3 plugins are assigned new plugin IDs in our registry, so it looks like many of our VST3 plugins won't load. All we need to do is re-scan our plugins manually. You can do this by clicking Options > Preferences > VST Plugins and click Refresh. Keep in mind that this scan will take some time, as again most of the plugins are being given new plugin IDs, but after that initial scan, your plugin scan at startup should be faster than they've ever been in SF. I hope this is helpful for you all!
