An important session in Studio Pro would not open, it stalled at loading a plugin. If I deleted that plugin, it just stalled at another plugin … Even if I opened an older version of the session, as soon as I had saved it, the older session too would not open. I spent a full day trying to recover that session. Finally I asked ChatGPT, and we found out that Tonex 2.02 was the problem. As soon as it was removed my session would load normally. Here is the message from ChatGPT:
Studio Pro 8.1.2 / macOS 26.5.2: session containing TONEX 2.0.2 can become unloadable after saving. During loading, Studio Pro appears to stall on apparently unrelated third-party plug-ins. Activity Monitor Sample Process shows the main thread blocked inside TONEX. Removing TONEX makes the session load normally and the subsequently saved session remains loadable.
