So, I finally decided to take the plunge and switch to Studio 2022. Alas, when I try to start it (after installation) I only get the above mentioned "Cannot validate SDL plug-in" error message.
Oddly enough, the beta version start just fine (and my trusted Studio 2021 is not impacted, phew).
Any idea what's going on?
