Cannot Connect to the Audio Engine again

I just did the crossgrade. Dorico Pro 5 was working fine until I deleted a flow folder for a midi file. I emptied the trash, so I cannot bring the folder back, but it opens fine most of the time. Can you check the diagnostic file and see what is happening? I don’t want to reinstall everything.

Hi @hauck.josh ,
thanks for the data, but even from that I can’t really say what is going on. The audio engine log says that it shuts down gracefully, but Dorico is still running and tries to connect to the audio engine that just went away…
How reliably can you reproduce the issue? Thanks

I can reproduce this issue very reliably.

Anytime I export a midi file and then delete the flow folder, it will happen. It has to be a bug that hopefully can get fixed down the road. Here is the diagnostics log a second time.

Thanks Josh, I"ll try to reproduce that myself. If I don’t succeed, can we have a remote screen sharing session? But no obligation, if you don’t want, please tell me frankly.

Yes, we can do that. I notice it created a Diagnostic Report for VST Audio Engine 5. I attached it.
