Hi, my issues seem quite different from yours in that I have no issue loading projects, however the audio engine is dropping out when recording.
However, the first thing I would ask is what your setup is - are you using some kind of audio interface? And are you using ASIO drivers specifically for that interface? If you are, maybe try ASIO4ALL and see if you can load projects with that instead of your device's default drivers.
Also, not everyone is having the issues I'm having which suggests the problem may not be widespread. I'm certainly not the only person experience the issue, however some people are seemingly not having the problem.
