For what it’s worth, I was able to get Opal working in 12.2.b17 by installing Max 9.0.4 (but strangely not 9.0.5) and making it the Max Application in Settings > File & Folder. Not an ideal solution but at least it gets the job done and you can always switch back over to 9.0.6 in projects where you aren’t using Opal…
